Antenna Switching Diversity Circuit for Car-Use FM Tuners

SANYO -> Panasonic 

Sample Application Circuit 1

LA1060

When the SW is placed in the 300kΩ position, the antenna is

held on the pin 8 side at the weak input signal mode.

When the SW is placed in the 10kΩ position, the antenna

holding function at the weak input signal mode does not work.

Unit (resistance : Ω, capacitance : F)

Component Placement Diagram

Circuit to cause the separation control

at the MPX stage to be entered into the

forced monaural mode when the

antenna switching frequency is high.

The antenna switching trigger pulse at

pin 6 is peak-held, integrated, and

attacks the separation control pin.

R1, Q1, R5, R10, R11 are connected to the Cu-foiled side.

(Because no holes are made.)

No.2650-4/8
