MULTIFUNCTION RECEIVER-ON-CHIP FOR ELECTRONIC WARFARE APPLICATIONS

摘要

The feed for the subject receiver-on-chip is a 30 Mhz to 18 Mhz Rf input (42), which is coupled to an RF pre-select and attenuation or notch filter circuit (44), which is off-chip. The out put of this circuit is amplified by a low noise amplifier LNA (46) and is either switched between a low band pass filter (48) or mixer (50) is used in a single down conversion stage, with the mixer (50) being driven by either 8, 10 or 12 GHz local oscillators on line (52) from a clock and local oscillator (54).
