摘要：
Design and performance of the mobile unit for the 800 MHz band land mobile telephone system is described. The mobile unit consists of a transceiver unit and a logic unit. Automatic frequency tuning of 600 radio channels is realized by a digital frequency synthesizer. The RF output power is 5W receiving sensitivity is below 0 dB mu . The logic unit, which provides automatic signaling and transceiver unit control, is composed of a stored program type circuit with a microprocessor.
