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, +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 addition, 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.
