The Mini-Circuits MAR-6SM+ MMIC is small but powerful. It has a bandwidth from DC to 2GHz, a gain of 22dB at HF frequencies, a very-low noise figure of 2.3dB, and–wait for it–a termination-insensitive I/O of 50Ω. It runs on 3.5VDC at 16mA. It’s pretty small, but it will come pre-installed on a half-inch square PCB similar to our BFR106 and dual-gate MOSFETs.
