RF/IF CIRCUIT AM/FM RADIO
TEA5570 monolithic integrated radio circuit portable receivers clock radios also applicable mains-fed AM/FM receivers radio-receivers Apart from' AM/FM switch function incorporates double balanced mixer, 'one-pin' oscillator amplifier with a.g.c. detector, level detector tuning indication. circuitry comprises i.f. stages with symmetrical limiter ratio detector. level detector mono/stereo switch information and/or indication complete part.
Simple d.c. switching only d.c. contact ground switch contacts i.f. channel, a.f. level detector outputs)
gain control current consumption (ltot voltage operation Ability handle large signals; good i.f. suppression Applicable inductive, capacitive diode tuning Double smoothing a.g.c. line Short-wave range
Lumped distributed i.f. selectivity with coil and/or ceramic filters a.g.c. output voltage control Distribution wiring provides good frequency stability Economic design only' receivers
