Description
The ACA0861 family of surface mount monolithic GaAs RF Linear Amplifiers has been developed to replace,
in new designs, the standard CATV Hybrid amplifiers currently in use. The MMICs consist of two parallel
amplifiers, each with 12 dB gain. The Amplifiers are optimized for exceptionally low distortion and noise
figure while providing flat gain and excellent input and output return loss. There are four differently specified
Amplifiers available, two input stages and two output stages. The ACA0861A and the ACA0861C are input
stages and are specified at +34 dBmV flat output. The ACA0861B and ACA0861D are output stages and are
specified at +44 dBmV flat output. A Hybrid equivalent is formed when one input stage ACA0861 is cascaded
with an ACA0861 output stage between two transmission line baluns. For low gain applications a single
ACA0861 can be used between baluns, for higher gain applications more than two ACA0861 can be
cascaded between baluns. See ACA0861 application note for more information.

Input Stages
The ACA0861A and the ACA0861C are designed as input stages and are specified at +34 dBmV flat output.
These parts can be used alone for low gain, low output level applications or can be cascaded with one of the
ACA0861 output stages for higher gain and output signal drive level. The ACA0861A is a low power dissipation
part designed to drive the ACA0861B output stage. The ACA0861C is a slightly higher power dissipation part
and provides the needed distortion parameters to drive the ACA0861D output stage.
Output Stages
The ACA0861B and ACA0861D are designed as output stages and are specified at + 44 dBmV flat output.
These parts can be used alone for low gain, high output level applications or can be cascaded with one of the
ACA0861 input stages for higher gain. The ACA0861B is a low power dissipation part designed as the output
stage with an ACA0861A input stage. The ACA0861D is a higher power dissipation part designed as the
output stage with an ACA0861C input stage. An ACA0861A and ACA0861B cascaded provide exceptional
push-pull hybrid equivalent performance, an ACA0861C and ACA0861D cascaded provide exceptional power
doubling hybrid equivalent performance (see Figure 2).

Notes:
1. Measured performance of MMIC alone. Balun effects de-imbedded from measurement.
2. Measured with a balun on input and output of the device. See Figure 1 for test setup.
3. All parts measured with 110 channel flat input. Parts A & C measured at +34 dBmV output. Parts B & D
measured at 44 dBmV output (per channel).
4. A fixed resistor is needed for parts A through C, part D does not need an external resistor. These resistors
set the devices’ current draw. Bias voltage is 12 VDC.

Description
The ACA1205 is a surface mount monolithic GaAs RF Linear Amplifier that has been developed to replace,
in new designs, the standard CATV Hybrid amplifiers currently in use. The MMIC consist of two parallel
amplifiers, each with 15 dB gain. The Amplifier is optimized for exceptionally low distortion and noise figure
while providing flat gain and excellent input and output return loss.

Input Stages
The ACA1205 is designed as an input stages. This part can be used alone for low gain, low output level
applications or can be cascaded with one of the ACA0861 output stages for higher gain and output signal
drive level. The ACA1205 is a low power dissipation part designed as a driver for the ACA0861B output stage.

FEATURES
Description
The ACD0900 MMIC is a high performance downconverter fabricated entirely in GaAs. It is designed for use
as the 2nd conversion stage in double-conversion tuners and cable modems, downconverting 900 -1200
MHz RF inputs to a fixed IF of 35 - 150 MHz (depending on LO frequency).
The IC incorporates a low noise amplifier, high linearity double balanced mixer, phase splitter and oscillator
in a SOIC 16 lead surface mount package. The high degree of functionality allows tuner manufactures to
reduce size and cost by lowering the component count and decreasing the amount of production alignment
steps, while significantly improving performance and reliability.

Description
The ACD2200 uses both GaAs and Si technology to provide the downconverter and dual synthesizer functions
in a double conversion tuners gain block, local oscillator, balanced mixer and dual synthesizer. The
specifications meet the requirements of CATV, TV and Cable Modem Data applications.
The ACD2200 is supplied in a 28 lead SSOP package and requires a single +5V supply voltage. The IC is
well suited for situations where small size, low cost, low auxiliary parts count and a no-compromise
performance is important. It provides for cost reduction by lowering the component and packaged IC count
and decreasing the amount of labor-intensive production alignment steps, while significantly improving
performance and reliability.

Register Programming with Serial Data
Programmable reference dividers (RF1 and RF2 Counters)
If the control bits are 00 or 01 (00 for RF2 and 01 for RF1) data is transferred from the 22-bit shift register into
a latch which sets the 15-bit R Counter. Serial data format is shown below.

Description
The ACU2109 is a Monolithic GaAs IC incorporating all upconverter functions of a double conversion CATV,
Cable Modem and TV tuner: gain block, oscillator and a double balanced mixer. The oscillator is optimized
to meet the stability and phase noise requirements of 256QAM Digital TV, while the
amplifier and mixer retain the low distortion necessary for Analog signals.
The part is supplied in a low profile 16-lead modified SOIC package and it requires only a single polarity 5
Volt power supply. This upconverter IC is well suited for double conversion tuner designs where small size,
low cost, low auxiliary parts count and a no-compromise performance when
handling both Digital and Analog TV signals is important.
It lets tuner manufacturers reduce costs by lowering component count and dispensing with labor-intensive
production alignment steps, while improving performance and reliability.

CATV Upconverter Module
Advanced Product Information - Rev 1
Gilbert cell mixer including LNA.
Wideband VCO and LO buffer to mixer.
Internal varactor and resonator circuit.
Internal 1087.75 MHz first IF SAW filter
with differential input & output.
Shielded metal lid over a LCC
(7.6mm x 10.2mm).
Description
The ACU2110 is a CATV upconverter module, that when used with a synthesized downconverter, allows
integrating the tuner on the same PC board along with the rest of the electronics for data applications. These
applications included digital video, telephony, and cable modems. The module consists of a modified GaAs
upconverter, SAW filter, and varactor diode in a hermetic LCC package.

Description
The ACU50752 is a Monolithic GaAs IC designed to perform the upconverter functions in a double conversion
tuner: gain block, local oscillator and balanced mixer. The specifications meet the requirements of CATV, TV
and Cable Modem applications. Supplied in a 16-lead SOIC package and requiring only a single polarity 5 V
supply (or 3.5 V, with slightly reduced performance), the IC is well suited in situations where small size, low
cost, low auxiliary parts count and a no-compromise performance is important. It provides tuner manufacturers
the opportunity to reduce cost by lowering the component count and decreasing the amount of labor-intensive
production alignment steps, while significantly improving performance and reliability.

modulation types.
Frequency range: 5 - 100 MHz.
Gain: 0 - 30 dB, variable in 2 dB steps.
5 Volt operation.
Low noise figure.

Description
The ARA05050 is a GaAs IC designed to perform the reverse path amplification and output level control
functions in a CATV Set-Top Box or Cable Modem. It incorporates a digitally controlled precision step
attenuator that is preceded by an ultra low noise amplifier stage, and followed by an ultra-linear output driver
amplifier. It is capable of meeting the MCNS/DOCSIS harmonic distortion specifications while only requiring
a single polarity +5V supply. This part is a single ended design that does not require an output balun to
achieve -55 dBc 2nd harmonic performance at +58 dBmV output levels. Both the input and output are
matched to 75 ohms. The precision attenuator provides up to 30 dB of attenuation in 2 dB increments. The
ARA05050 is supplied in a 28-pin SSOP package featuring a thermal heat slug on the bottom of the package.
Soldering this heat slug to the ground plane of the PC board ensures the lowest possible thermal resistance
for the device resulting in a long MTF.
