General Description
Pin Configuration
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 ½W 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 5x5mm 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.
The TQM8M9074 is targeted for use in wireless
infrastructure where high linearity, medium power, and
high efficiency are required.
