Features and Functions
• Contains RF amplifier, MIX, OSC, AFC diode.
• Operating voltage : 1.8 to 8.0V.
• Improvement in cross modulation characteristic due to the
use of double-balanced MIX.
• Improvement in strong input characteristic.
• Minimum number of external parts required.
• Less spurious radiation from local OSC.
• TV (1 to 12 channel) receive capability.
