The APTC4-01001800-1905-D4 from AmpliTech is a Low Noise Cryogenic Amplifier that operates from 1 to 18 GHz. It provides a gain of more than 30 dB with a noise figure of less than 2 dB and has a P1dB of over 5 dBm. The amplifier uses State-of-the-Art pHEMT technology and is designed for cryogenic applications down to 4°K. It requires a DC supply voltage of 9 V, draws 60 mA of current, and consumes 819 mW of power at 296°K. The LNA is available in a MIL-883 and MIL-45208 standard module with SMA-female connectors. It is ideal for use in radiometers, nanophysics (especially for electron spin resonance), astronomy and observatory receivers, superconductor research, and satellite receivers.
An optional super slim version is also available for low profile, stackable solutions with miniature 0.9 mm threaded connectors for high integrity connections.
