1 / 8 page LA1061M Ordering number : EN3044A Antenna Switching Controller Monolithic Linear IC SANYO Electric Co.,Ltd. Semiconductor Bussiness Headquarters TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110 JAPAN 82997HA (KT)/9070TA/6019TA, TS No.3044-1/8 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. Package Dimensions unit: mm 3111-MFP14S [LA1061M] SANYO: MFP14S Features • Uses Sanyo's proprietary AGC amplifier and detector, providing accurate detection of multi-path distortion. • High-current Main and Sub-antenna switching outputs. • Antenna switching frequency limiting circuit. • On-board comparators for F.E AGC (strong signal) and S-meter DC (weak signal) detection. • Surface-mount 14-pin MFP.
