MC13135P

The MC13135P is the second generation of single chip, dual conversion FM communications receivers which is devel oped by Motorola. Major progresses in signal handling, RSSI and first oscillator operation have been made. What's more, recovered audio distortion and audio drive have improved. These receivers provide low noise, high gain and stability over a wide operating voltage range, and Lansdale is pleased to continue to provide them.

Features of the MC13135P are:(1)complete dual conversion FM Receiverantenna to audio output;(2)input frequen cy range is 200 MHz;(3)voltage buffered RSSI with 70 dB of usable range;(4)low voltage operation 2.0 to 6.0 Vdc (2 cell nicad supply);(5)low current drain is 3.5 mA typ;(6)low impedance audio output is less than 25 ;(7)VHF colpitts first LO for crystal or VCO operation;(8)isolated tuning diode;(9)buffered first LO output to drive CMOS PLL synthesizer.

The absolute maximum ratings and electrical characteristics(TA = 25°C, VCC = 4.0 Vdc, fo = 49.7 MHz, fMOD = 1.0 kHz, Deviation = ±3.0 kHz, f1stLO = 39 MHz, f2nd LO = 10.245 MHz, IF1 = 10.7 MHz, IF2 = 455 kHz)of the MC13135P can be summarized as:(1):power supply boltage is 6.5Vdc;(2):RF input voltage is 1.0 Vrms;(3):junction temperature is+150 °C;(4):storage temperature ranges from65°C to +150 °C.Electrical characteristics:(1):total drain current is 4.0mAdc typ and 6.0 mAdc max of no input signal;(2):sensitivity (input for 12 dB SINAD)is1.0 Vrms typp;(3):reco vered audio is 170mVrms min, 220mVrms typ and 300 mVrms max;(4):1st mixer conversion gain is 12dB when VRF is40 dBm;(5):2nd mixer conversion gain is 13 dB when VRF is40 dBm.etc.
