TQC9305 0.7 3.6 GHz Digital Variable Gain Amplifier General Description The 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, 32 Pin 5X5 mm Leadless SMT Package +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 Product Features and low noise figure. In addition, the DVGA integrates a shut-down biasing capability to allow for easy operation for Integrates DSA + Amp Functionality TDD applications. 0.7 3.6 GHz Broadband Performance The TQC9305 integrates a high performance digital step 5-bit control, 31 dB range attenuator followed by a high linearity, broadband gain 13 dB Gain at 1.9 GHz block. Both stages are internally matched to 50 Ohms and 3.1 dB Noise Figure at max gain setting do not require any external matching components. The +23 dBm P1dB TQC9305 is packaged in a RoHS-compliant, compact 5x5 +27 dBm IIP3, +40 dBm OIP3 mm surface-mount leadless package.
