General Description
The TQM8M9074 is a high dynamic range analog
controlled variable gain amplifier (VGA) which operates
from 0.7 to 2.8 GHz. The VGA is able to achieve high
performance with +43 dBm OIP3 and +27.5 dBm P1dB
over a wide gain variation range while only consuming
225 mA current.
The TQM8M9074 integrates a high linearity, low noise
amplifier for the first stage, followed by a broadband
voltage variable attenuator, and then with a high
performance ½ W P1dB amplifier. The input and output
of the various individual stages are accessible with
external pins to allow for optimization of performance at
any sub-band across the VGA’s 0.7 to 2.8 GHz
operating frequency range. The TQM8M9074 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 TQM8M9074 is targeted for use in wireless
infrastructure where high linearity, medium power, and
high efficiency are required.
