Qorvo's TQC9311 is a dual-channel, digitally-controlled variable gain amplifier (DVGA) operating over a broadband frequency range of 400 to 3600 MHz. The DVGA features 36.5 dBm OIP3 while providing digital variable gain with 31.5 dB of gain range in 0.5 dB steps through a 12-bit serial mode control interface. This combination of performance parameters makes the DVGA ideal for diversity or MIMO receiver applications requiring gain control with high linearity and low noise figure.
The TQC9311 integrates a high performance digital step attenuator followed by a high linearity, broadband gain block in a dual-channel configuration. The dual channel DVGA is internally matched to 50 Ohms and does not require any external matching components. Bias choke inductors and bypass/blocking capacitors are also integrated into the module thereby reducing the number of external components needed. The TQC9311 is packaged in a RoHS-compliant, compact 7x7 mm surface-mount leadless package.
