The APTC3-04000800-1K00-D4-V from Amplitech is a Low Noise Cryogenic Amplifier that operates from 4 to 8 GHz. It provides a gain of more than 40 dB with a noise figure of 0.35 dB and has a P1dB of -6 dBm. The amplifier requires a DC supply of 0.7 V and draws 20 mA of current (typical) while consuming 2.5 mW of power at 4°Kelvin. It is fabricated using state-of-the-art PHEMT technology and is designed for cryogenic applications down to 1°K. This MIL-883, MIL-45208 certified LNA is available in a module with SMA Female connectors and is ideal for quantum computing, radiometers, nanophysics (electron spin resonance), astronomy/observatory receivers, superconductor research, and satellite receiver applications.
