Qorvo's TQC9312 is a digital variable gain amplifier (DVGA) featuring high linearity over the entire gain control range. This amplifier module integrates two gain blocks, a digital-step attenuator (DSA), and a high linearity 0.5 W amplifier. The module has the added feature of integrating all matching components, bias chokes and blocking capacitors. 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.
The TQC9312 features variable gain from 9 dB to 40dB at 3.5 GHz, +44.5 dBm output IP3, and +27.8 dBm P1dB. The module operates from a single +5V supply and is available in a compact 28-pin 6x6 mm leadless SMT package.
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 type of device for specific system level requirements as well as making the DVGA family ideal for applications where a common PCB layout is used for different frequency bands.
Typical Applications
- Base Station Transceivers
- DAS
