Qorvo's TQC9307 is a digitally controlled variable gain amplifier (DVGA) with a broadband frequency range of 500 to 4000 MHz. The DVGA features high linearity and low noise while providing digital variable gain with a 31 dB of range in 1 dB steps through a serial mode control interface. At 3.5 GHz, the DVGA typically provides 13.3 dB gain, +40.5 dBm OIP3, +21 dBm P1dB, and 3.5 dB noise figure. The DVGA features positive gain slope across the 3.3-3.8 GHz frequency range which is very common for a VGA. In addition, the DVGA integrates a shut-down biasing capability to allow for easy operation for TDD applications.
The TQC9307 integrates a high performance digital step attenuator followed by a high linearity, broadband gain block. Both stages are internally matched to 50 ohms and do not require any external matching components. The TQC9307 is packaged in a RoHS-compliant, compact 5x5 mm surface-mount leadless package.
