摘要：
We consider the structure of a small-size superheterodyne modulation-type radiometric receiver with a low-noise transistor amplifier (LNTA) at the input. With LNTA noise coefficient 3.5 dB, the fluctuation sensitivity of the radiometric receiving unit was 0.025 K in the input-frequency range 56-60 GHz for a time constant 1 s.
