Overview

The LA1061M is an antenna switching controller for

mobile radio equipment.

The LA1061M uses a number of inputs from the receiver

circuitry to select the main antenna or sub-antenna

according to signal strength and quality. Weak and strong

signals are detected with the S-meter DC voltage and F.E.

AGC voltage, respectively. Multi-path distortion is

detected from the AC component of the IF output, using

the same high-sensitivity counter circuit as in Sanyo's

earlier LA1060 device. An auxiliary circuit keeps the main

antenna selected for a fixed time period when reception

conditions outside a moving vehicle are changing rapidly.

The LA1061M is available in surface-mount 8-pin DIPs,

facilitating construction of compact equipment. It operates

from a single 7 to 12V power supply.
