This amplifier module integrates two gain blocks, a Pin Configuration digital-step attenuator (DSA), and a high linearity W amplifier. The module has the added feature of Pin No. Label integrating all matching components, bias chokes and 1 LE blocking capacitors. The internal 6-bit DSA provides a 2 DATA 31.5 dB gain control range in 0.5 dB steps, and is 3 CLK TM controlled with a serial periphery interface (SPI ). 4, 22 NC 6 RFIN The TQC9312 features variable gain from 9 dB to 40dB 8 VCC AMP1/AMP2 at 3.5 GHz, +44.5 dBm output IP3, and +27.8 dBm 14 VCC AMP3 P1dB. The module operates from a single +5V supply 16 RFOUT and is available in a compact 28-pin 6x6 mm leadless 28 VCC SPI SMT package. 5, 7, 9-13, 15,17-21, 23-27 GND Backside Pad GND The TQC9312 is pin compatible with the TQM879008 (1.5-2.7GHz, 0.5W P1dB) and TQM879006A (1.4- 2.7GHz, 0.25W P1dB). This allows one to size the right Ordering Information type of device for specific system level requirements as well as making the DVGA family ideal for applications Part No. Description where a common PCB layout is used for different TQC9312 3.3-3.8 GHz DVGA frequency bands.
