Receiver AM / FM IC SA2132

Tuesday, October 31st, 2017 - RF Circuit

Radio receiver AM / FM IC SA2132 is very simple and use one type of fruit receiver IC SA2132. IC SA2132 is an IC chip designed specifically as a receiver or a receiver AM / FM radio with a low DC voltage source of 1.8 volts to 8 volts DC. The circuit of radio receiver AM / FM IC SA2132 use with variable frequency control oscillator capacitor (Varco). The circuit of receiver AM / FM IC SA2132 in the figure below is part of a receiver circuit that still require a stereo FM demodulator and audio amplifier. Schematic diagram and lists of components to assemble the radio circuit receiver AM / FM IC SA2132 can be seen in the following figure.

To select the work mode on the AM or FM radio with FM receiver IC SA2132 fairly by giving logic HIG / LOW on track AM / FM switch IC SA2132. A voltage source for the radio circuit receiver AM / FM IC SA2132 This uses 2 AA batteries or using a power supply with an output voltage range of 1.8 – 8VDC.

Feature Of Receiver AM / FM IC SA2132 accordance Datasheet:

  • Operating supply voltage range: VCC = 1.8 ~ 8V (additions = 25 ° C)
  • For NEW FCC
  • AM detector coil without FM IFT, IF coupling condenser.
  • Adopting for ceramic discriminator, it is not the need to adjust the FM quad detector circuit.
  • Built in varactor diode for AFC
  • Low supply current (VCC = 3V, additions = 25 ° C)
    • ICCq (FM) = 7.3mA (typ.)
    • ICCq (AM) = 3.6mA (typ.)

To get the stereo audio signal from the circuit receiver AM / FM IC SA2132 above should be added to the FM demodulator circuit.
