AmpliTech Announces Cryogenic, Ultra Low Noise Amplifiers

Holbrook, NY -- AmpliTech has begun offering its cryogenic amplifiers designed to operate at extremely low temperatures (below the Liquid Helium temperature of 16 degrees K or -257 degrees C) in order to take advantage of the decreased noise figures at those levels. In essence, a signal goes into the amplifier and the exact same amplified signal comes out.

Cooling these amplifiers takes up a lot of energy. To minimize the consumption of this energy, the company has designed a cooler running amplifier. that offers low DC voltage options (as low as +3 VDC), low current consumption, and a lightweight, compact housing.

The APTC2-04000800-0700-D4-S cryogenic amplifier consumes 3VDC/40mA of power and features NF, flat gain, output power, and VSWR at both room and cryogenic temperatures. It can be further modified for other frequencies and specs. Another design is the APTC4-00101800-1910-D4, which is an ultra-wide band LNA covering the frequency of 0.1 to 18.0 GHz.

These amplifiers are suited for applications requiring the lowest amounts of noise injection - such as RF imaging, research and development, deep space communications, accelerators, and radar. Noise figures as low as 0.07 dB (<5° K) are possible at L-band frequencies. Custom solutions are available. Cooling systems are also available for all cryogenic amplifiers.

AmpliTech will be exhibiting these amplifiers during MTT-S, June 3 - 7 in Honolulu, booth #713.
