A 2.5 mW D‐Band Broadband Simultaneous Noise‐ and Input‐Matched InP LNA

Electronics Letters, Volume 62, Issue 1, January/December 2026.
This work presents a D‐band, ultra‐low‐power, broadband two‐stage low‐noise amplifier (LNA) implemented in a 250‐nm InP DHBT process. Using a simultaneous noise and input matching technique with a gain‐boosted feedback network, the LNA achieves 6.2 dB noise figure and 27 dB gain from 130 to 155 GHz while consuming only 2.5 mW.
