Abstract: The invention discloses design of the wideband single, dual or three channel signal detector with ability to suppress interference and crosstalk from two PLL LO signal generators (101 & 102) with selection of best pairs of LO frequencies (108 & 109) out of all possible pairs in the way that all interference is kept out-of-band and with efficient filtering in IF (103) and baseband (104) to achieve high sensitivity for wideband channels without requirement for heavy shielding or adding of absorptive materials to the receiver subsystems. Method for measurement and creating array with frequency pairs to control PLL generators with optimal frequency distribution on each PLL generator for uniform and fastest possible scanning of all required bands is also disclosed.
