General Description
The 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.

All other pins are internally grounded.
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 7 x 7 mm surface-mount leadless package.
