General Description
Pin Configuration
The TQM8M9077 is a digitally controlled variable gain
amplifier (DVGA) with a broadband frequency range of 50
to 4000 MHz. The DVGA features high linearity and low
noise while providing digital variable gain with a 31.5 dB
of range in 0.5 dB steps through a 6-bit serial mode control
interface. This combination of performance parameters
makes the DVGA ideal for receiver applications requiring
gain control with high IIP3.
The TQM8M9077 integrates a high performance digital
step attenuator and a high linearity, broadband gain block.
Both stages are internally matched to 50 Ohms and do not
require any external matching components. A serial output
port enables cascading with other serial controlled devices.
The TQM8M9077 is packaged in a RoHS-compliant,
compact 5x5 mm surface-mount leadless package.
Superior thermal design allows the product to have a
minimum MTTF rating of 1000 years at a mounting
temperature of +85º C.
