Description

 

 

CMT’s new enhanced cryogenic low noise amplifier, the CITCRYO4-12B, has been designed to meet the requirements for quantum applications.

 

 

A SUBSTANTIAL ADVANCEMENT

  • The CITCRYO4-12B can achieve a noise temperature of 4 K through a 4 to 12 GHz frequency band.

  • Its lowest noise temperature measured is 2.5K with a gain of 35 dB, which is a substantial advancement from the original CMT’s CITCRYO4-12A.

  • In its standard configuration, it comes with female SMA connectors on the RF-input and output and a 4-pin 2 mm pitch header for the DC. The amplifier requires three (3) separate DC-voltages.

 

LOW POWER CONSUMPTION

  • The amplifier can achieve a very low power consumption as low as 4 mW with a noise temperature of less than 6 K from 4 to 6 GHz.

  • Its input return loss is less than 10 dB throughout this frequency band.
