Pin Configuration
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
TM
serial periphery interface (SPI ). The individual stages
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
TM
The TQM879028 has a CMOS SPI input compatible serial interface. This serial control interface converts the serial
TM
data input stream to parallel output word. The input is 3-wire (CLK, LE and SID) SPI 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.

Notes:
1. All dimensions are in millimeters. Angles are in degrees.
2. Use 1 oz. copper minimum for top and bottom layer metal.
3. 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”).
4. Ensure good package backside paddle solder attach for reliable operation and best electrical performance.
