CITCRYO4-12B
Cryogenic HEMT Low Noise Amplifier
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 2.5 K 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.
