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 a 31.5 dB
of range in 0.5 dB steps through a 6-bit serial mode control
interface.
The TQM8M9076 integrates a high performance digital
step attenuator followed by a high linearity, broadband gain
block. The input and output of the individual stages are
accessible with external pins to allow for optimization of
performance at any sub-band across the DVGA’s 0.05 to
4.0 GHz operating frequency range.
The TQM8M9076 is packaged in a RoHS-compliant,
compact 5x5 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 +85º 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
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 SERIN) SPITM input compatible. At power up, the
serial control interface resets device attenuation state to 31.5dB. The 6-bit SERIN word is loaded into the register on rising
edge of the CLK, MSB first. When LE is high, CLK is disabled.
