Description
TQM8M9076 Digital Variable Gain Amplifier
TQM8M9076-PCB
0.3 – 4.0 GHz Evaluation Board
Standard T/R size: 2500 pieces on a 13” reel
Gener a l Des cr iption
The TQM8M9076 is a digitally controlled variable gain
amplifier (DVGA) with a broadband frequency range of
50 to 4000 MHz
The DVGA features high linearity and
low noise while providing digital variable gain with
31.5 dB of range in 0.5 d
B steps through a 6-
bit serial
mode control interface.
This combination of
performance parameters makes the DVGA ideal for
receiver applic ations r equ iring g ain c ontrol with h igh II P3
and low noise figure.
The TQM8M9076 integrates a high performance digital
step attenuator
and
a high linearity, broadband gain
block.
Both stages are internally matched to 50 Ohms
and do not require any external matching components.
A serial output port enables cascading with other serial
controlled devices.
The
TQM8M9076 is packaged in a RoHS-
compliant,
compact 5 x 5 mm surface
-mount
leadless package.
Superior thermal design allows the product to have a
minimum MTTF rating of 1000 years at a mounting
temperature of +85 °C.
The
TQM8M9076
is targeted for use in wireless
infrastructure, point
-to-
point, or can be used for any
general purpose wireless application.

0.05 – 4 GHz Digital Variable Gain Amplifier
Seria l Cont rol Interface
The TQM8M9076 has a CMOS SPITM input compatible serial interface. This serial control interface converts the serial
data input stream to parallel output word. The input is 3
-wire (CLK, LE and SID) S PITM input compatible. At power up,
the serial control interface resets the DSA to the minimum gain state. The 6
-bit SID (Serial Input Data) word is loaded
into the register on rising edge of the CLK, MSB first. When LE is high, CLK is internally di
sabled.

Notes:
1. All dimensions are in millimeters. Angles are in degrees.
1. Use 1 oz. copper minimum for top and bottom layer metal.
2. Vias are required under the backside paddle of this device for proper RF/DC grounding and thermal dissipation. We
recommend a 0.35mm (#80/.0135") diameter bit for drilling via holes and a final plated thru diameter of 0.25 mm (0.10”).
3. Ensure good package backside paddle solder attach for reliable operation and best electrical performance.
