CMT-BA1
NEW Cryogenic SiGe Low Noise Amplifier
Description
-
The CMT-BA1, a SiGe low noise amplifier, is intended for extremely low noise cryogenic applications. This amplifier is an upgrade from our LF1 amplifier. The optimum frequency range is 0.005 GHz to 1.5 GHz. The noise temperature is 2.0K @ 30 MHz with a maximum of 3.5K @ 1.5 GHZ. The typical gain of the amplifier is 34 dB with a gain flatness of +/-1 dB. High gain and low noise is achieved up to 4.2 GHz.

It is powered from a single positive DC power supply which is optimum at 2.0 V, but can be reduced to as low as 1.5 V for low power dissipation. Application of up to 3 V will not damage the amplifier. It is recommended that the power supply for the amplifier to be current limited to 100 mA.
