LA1061M
Antenna Switching Controller
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.
