Abstract
In a transceiver module, a micro wave analog signal interface is provided between the transceiver module and an antenna element, and all the signal interfaces except a power supply are digital signal interfaces, and the interfaces are configured as one chip on a semiconductor. An internal reference signal generates a local signal serving as a reference by multiplying a high frequency digital clock signal supplied from the outside, and simultaneously generates a reference signal capable of synchronous operation by a lower frequency digital clock signal supplied from the outside, in the clock generator. The frequency of the generated reference local signal can be varied by controlling the inner multiplication number or the frequency of the higher frequency digital clock signal supplied from the outside. In addition, both transmission and reception can be executed with an arbitrary frequency by varying the frequency of the transmission waveform generator.
