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. ACA0861-A,B,C,D 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).

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.

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.
