For Use With
TQM879028
The TQM879028 is a digital variable gain amplifier
(DVGA) featuring high linearity over the entire gain
control range. This amplifier module integrates a gain
block, a digital-step attenuator (DSA), and a high
linearity ½ Watt amplifier into a compact 4x4 mm
module. The internal 6-bit DSA provides a 31.5 dB gain
control range in 0.5 dB steps, and is controlled with a
serial periphery interface (SPI
are accessible to external ports to allow for optimization
of the last stage amplifier for individual bands and also
allowing other functional blocks to be added in-between
the stages.
The TQM879028 features variable gain from 0.5 dB to
32 dB at 2.14 GHz, +44 dBm output IP3, and +27.5 dBm
P1dB while only consuming 230 mA current from a 5V
supply. The module is available in a compact 24-pin 4x4
mm leadless SMT package.

... Serial Control Interface The TQM879028 has a CMOS SPI data input stream to parallel output word. The input is 3-wire (CLK, LE and SID) SPI 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. ...
