Qorvo 700 - 3600 MHz Serial Controlled Digital Variable Gain Amplifier w/ Shutdown Function, 5-Bit, 1 dB Steps, Packaged TQC9305

Qorvo's TQC9305 is a digitally controlled variable gain amplifier (DVGA) with a broadband frequency range of 700 to 3600 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 1.9 GHz, the DVGA typically provides 13 dB gain, +40 dBm OIP3, +23 dBm P1dB, and 3.1 dB noise figure. This combination of performance parameters makes the DVGA ideal for receiver applications requiring gain control with high IIP3 and low noise figure. In additional, the DVGA integrates a shut-down biasing capability to allow for easy operation for TDD applications. The TQC9305 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 TQC9305 is packaged in a RoHS-compliant, compact 5x5 mm surface-mount leadless package.
