Pin Configuration
The TQM879026 is a digital variable gain amplifier
(DVGA) featuring high linearity and digital variable gain
control in 0.5 dB step sizes. This DVGA integrates a
gain block, a digital-step attenuator (DSA), and a high
linearity ¼-watt amplifier into a compact 4x4 mm
package. The internal 6-bit DSA provides a 31.5 dB
gain control range and is controlled with a serial
TM
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 inbetween the stages.

Serial Control Interface
TM
The TQM879026 has a CMOS SPI input compatible serial interface. This serial control interface converts the
TM
serial 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.

PCB Mounting Pattern
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.
4. Do not remove or minimize via hole structure in the PCB. Thermal and RF grounding is critical.
5. 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”).
6. Ensure good package backside paddle solder attach for reliable operation and best electrical performance.
