| Abstract: | To recover the video signal from the modulated IF of wide bandwidth and large intensity difference, the detector should have the characteristics of wide bandwidth, and large dynamic range, high linearity fidelity. The theory and the performance of the wide bandwidth linear detector in the wide bandwidth receiver are introduced. The implementation of the wide bandwidth linear demodulation circuit is analyzed in terms of performance specifications on bandwidth, linearity fidelity and dynamic range. |
