Single Stage Cryogenic SiGe Low Noise Amplifier

  • The CMTLF1s, a single stage SiGe low noise amplifier, is intended for extremely low noise cryogenic applications. The amplifier uses resistive feedback to achieve good input match (S11) and high gain stability. The amplifier is optimum for the frequency range of 0.001 GHz to 2.0 GHz. 


  • It is powered from a single positive DC power supply which is optimum at 3.0 V.


  • The amplifier is 22.2 mm x 10.16 mm x 8.59 mm, excluding connectors. Input and output female SMA connectors.
