　　General Description

　　The TQM8M9079 is an analog controlled variable gain amplifier （VGA） which operates from 500 to 2700 MHz. The VGA is able to provide broadband performance with +29 dBm OIP3 and +16 dBm P1dB over a wide frequency range while only consuming 95 mA current.

　　The TQM8M9079 integrates two broadband gain blocks with a voltage variable attenuator. The three stages are individually accessible via package I/O contacts. This permits full flexibility to insert other components or filters between the stages.

　　The TQM8M9079 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 TQM8M9079 is targeted for use in wireless infrastructure， IF gain control in point-to-point applications， and for general purpose wireless.
