General Description
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
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 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 5 x 5 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 TQM8M9077 is targeted for use in wireless
infrastructure, point-to-point, or can be used for any
general purpose wireless application.
