Applications
Wireless Infrastructure
Fixed Wireless
Microwave and Satellite Radio
IF and RF Applications
General Purpose Wireless
32 Pin 5 x 5 mm Leadless SMT Package
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.

General Description
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 dB steps through a 6-bit serial
mode control interface.
This combination of
performance parameters makes the DVGA ideal for
receiver applications requiring gain control with high IIP3
and low noise figure.

Serial Control 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) SPITM 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 disabled.

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.
