ABSTRACT:
A radio transmission and reception apparatus having a transmitting section and a receiving section for bidirectional data transmission between two end units in the time-division multiplex mode. Prior art radio transmission and reception apparatuses are equipped with a transmitting section and a receiving section that have separate PLL circuits for signal modulation and demodulation. The resultant expense for relatively expensive components can be considerably reduced in radio transmission and reception apparatuses if only one PLL circuit is provided in accordance with the invention, to which both the transmitting section and the receiving section have alternating access.
