Abstract
The present disclosure is directed to apparatus and method that extends a useful operation range of an amplifier circuit. Here a low noise amplifier may be attached to a cold end of a cooler or chiller, such as a “Stirling” cryocooler after which a chamber that encloses the cold end of the cooler and the amplifier may be assembled. Gas included in the chamber may be removed by attaching an input to a vacuum pump to a portion of the chamber. After the chamber is sealed such that a low pressure in the chamber can be maintained, the cooler may be turned on in order to chill the amplifier to temperatures that reduce noise generated internally to the amplifier or to reduce amounts of return loss associated with the amplifier. The use of a Stirling cryocooler allows for the amplifier to be cooled to very low or cryogenic temperatures.
