Ultra-Low-Noise Cryogenic PHEMT Amplifiers

Предложен новый подход к разработке криогенно охлаждаемых малошумящих усилителей в диапазоне 0.5-4 ГГц. Особое внимание уделено устойчивости и шумовым характеристикам при криогенных температурах. При охлаждении до 20-80 К шумовая температура представленных устройств составляет единицы градусов Кельв...
