FM IF MW radio receiver circuit using LA1260 IC
A very simple FM IF MW radio receiver circuit can be designed using the LA1260 IC manufactured by Sanyo Semiconductor .
As you can see in this FM IF MW radio receiver circuit schematic the LA1260 ic can be used in AM FM radio receiver electronic projects .LA1260 has integrated in the package many functions and features that are needed for radio receiver applications .
Some important functions of LA1260 FM IF MW radio receiver circuit are :
FM : IF amplifier, quadrature detector, AF preamplifier, tuning indicator drive output.
AM : RF amplifier, MIX, OSC (with ALC), IF amplifier, Detector, AGC, tuning indicator drive.
Some of the main important features of the LA1260 FM AM tuner system are:
high S/N : FM 81dB ,AM 53dB ;low-level AM oscillator with ALC MW 130mV SW 70 mV to 90 mV (7MHz) (24MHz) ;less AM whistle interference : whistle 1% at input 100dB/m. ;on-chip LED tuning indicator driver ;on-chip FM/AM selector; independent FM/AM output pins .
The AM local oscillation parts, AM local oscillation coil, and antenna circuit parts such as bar antenna must be separated from each other as far as possible to prevent Qs from worsening.
Pin 16 (AM oscillation injection pin) and pin 14 (RF input pin) must be separated from each other . The recommended power supply for this radio receiver circuit is 4.5 volt DC , but the LA1260 ic accepts an input voltage range from 3 to 8 volts DC .
