General Description
Pin Configuration
The TQM8M9075 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 and low noise figure.
The TQM8M9075 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 TQM8M9075 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 +85°C.
The TQM8M9075 is targeted for use in wireless
infrastructure, point-to-point, or can be used for any
general purpose wireless application.
