TQM829007
0.6-1.0GHz ¼W Digital Variable Gain Amplifier
The TQM829007 is a 50 Ω internally matched digital variable gain amplifier (DVGA) featuring high linearity over the entire
gain control range. The amplifier module features the integration of a low noise amplifier gain block, a digital-step attenuator,
along with a high linearity ¼W amplifier as shown in the functional diagram below. The module is unconditionally stable.
Internal blocking capacitors and bias structures keep external parts count to a minimum. The DVGA has an operational
frequency range from 0.6 – 1.0 GHz.
