Summary This paper investigates modeling of silicon‐germanium heterojunction bipolar transistor noise parameters and impedance‐matched Low‐Noise Amplifiers (LNAs) intended for operation across a wide temperature range (from 93 to 393 K). In general, noise performance improves with cooling until about 150 K, then degrades some because of carrier freeze‐out. With a temperature independent bias current, an LNA designed for 300 K operation shows acceptable performance from 93 to 393 K, albeit with some degradation of linearity below 120 K.
