• Manufacturer Part Number: ta7371afg
• Description: Fm Front?end
• Manufacturer: TOSHIBA Semiconductor CORPORATION

Explanation Of Inner Circuit And Functions
(1) RF block
(2) MIX block
(3) OSC block
The radio signal is applied to RF INPUT passed
through the ANT and BPF.
This RF block is composed of the common emitter
amplifier. The output is designed to be the cascade
connection, because of high sensitivity characteristic,
and excellent spurious radiation. (Fig.1)
The MIX block is composed of the emitter coupled
pair amplifier. (Fig.2)
OSC block is composed of the colpitts oscillation
circuit.
The capacitors C
1
and C
2
are built in this IC.
