CIRCUIT DESCRIPTION MC3359 low-power circuit designed primarily voice-communication scanning receivers. also finding place narrowband data links. typical application (Figure mixer-oscillator combination converts input frequency (10.7 MHz) down kHz, where, after external bandpass filtering, most amplification done. audio recovered using conventional quadrature detector. absence input signal indicated presence noise above desired audio frequencies. This "noise band" monitored active filter detector. squelch-trigger circuit indicates presence noise tone) output which used control scanning. same time, internal switch operated which used mute audio. APPLICATIONS INFORMATION oscillator internally biased Colpitts type with collector, base, emitter connections respectively. crystal used fundamental mode, calibrated parallel resonance load capacitance. theory this means that capacitors series should fact much larger values significantly affect oscillator frequency, provide higher oscillator output. oscillator also used conventional Colpitts configuration without loss mixer conversion gain. This oscillator course, much more sensitive voltage temperature shown Figure Guidelines choosing values given Figure mixer doubly balanced reduce spurious responses. mixer measurements Figure were made using external source internal Voltage gain curves several voltages shown Figure Third Order Intercept curves Figure shown using conventional scales. Measured power gain (with input) approximately useful gain much higher because mixer input impedance over Most applications will 10.7 crystal filter ahead mixer. higher frequencies, relative mixer gain given Figure Following mixer, ceramic bandpass filter recommended. types come bandwidths from have input output impedances this reason, input stage limiting internal resistor. limiting sensitivity approximately useful frequency range about shown Figure frequency limitation high resistance values which were necessary meet power requirement. output limiter internally connected quadrature detector, including quadrature capacitor. Only parallel needed externally from VCC. shunt resistance added widen peak separation quadrature detector. detector output amplified buffered audio output, which output impedance approximately provides high impedance point output amplifier application filter de-emphasis capacitor. output, with high gain high output impedance needed, should grounded, connected double recovered audio. detector responses shown Figure Overall performance MC3359 from mixer input audio output shown Figure MC3359 also operated "single conversion" equipment; i.e., mixer used amplifier. oscillator disabled connecting this mode, overall performance identical 10.7 results Figure simple inverting provided with output providing bias (externally) input which referred internally filter made with external impedance elements discriminate between frequencies. With external detector, filtered audio signal checked presence either noise above normal audio, tone signal. open loop response this given Figure13. Bandpass filter design information provided Figure bias sets squelch-trigger circuit that high, source least audio mute (Pin open-circuit. raised noise tone detector, becomes open circuit internally short circuited ground. There hysteresis. Audio muting accomplished connecting high-impedance ground-reference point audio path between audio amplifier. voltage needed, fact desirable because audio "thump" would result during muting function. Signal swing greater than below ground should avoided.
