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. |
