LOSS-LESS FREQUENCY DEPENDENT DICKE-SWITCHED RADIOMETER |
摘要 |
A Dicke-switched radiometer including a signal channel comprising of an antenna for receiving an input signal and a first stage amplification circuit for amplifying an output of the antenna and generating an amplified input signal; a reference channel comprising of a resistive load, a second stage amplification circuit and a matching filter for matching a frequency and an impedance of the amplified input signal to a frequency and an impedance of the amplified reference signal; a Dicke switch coupled to first stage amplification circuit and the matching filter for inputting the amplified input signal and an output of the matching filter to generate a difference signal; a third stage amplification circuit coupled to an output of the Dicke switch for amplifying the difference signal; and a detector coupled to an output of the third stage amplification circuit to obtain the amplified difference signal and generate a detected difference signal. |
