The APTC3-06000850-2K00-D2-V from AmpliTech is a Low Noise Cryogenic Amplifier that operates from 6.0 to 8.5 GHz. It has been designed for cryogenic applications down to 4K, with an industry-low Noise Figure of 25K at +296K and 2K at 4K case temperatures across the band. It provides a more than 40 dB of gain with a noise figure of less than 0.029 dB (at 4 K) and has a P1dB of -6 dBm. The amplifier is manufactured using state-of-the-art pHEMT technology and is compliant with MIL-883 and MIL-45208 military standards. It requires a DC supply of 0.5 V and consumes less than 20 mA of current.
This LNA is available in a module that measures 1.17 x 0.70 inches with SMA-female connectors and a low profile, stackable option is also available on request. It is ideal for use in quantum computers, radiometers, nanophysics (electron spin resonance), astronomy/observatory receivers, superconductor research, satellite receivers, and phased array antenna applications. It is also well suited for phased array antenna applications where ultra-low noise figure and low power dissipation is critical to the performance of the receiver gain and sensitivity.
