ABSTRACT:
A telecommunication arrangement for transmitting a first communicating signal and receiving a second communicating signal, particularly useful for sattelite communications. A transmitter generates a first transmitting signal at a first time and generates a second transmitting signal at a second time different from the first specified time. The first transmitting signal is mixed with an oscillating signal by a first mixer for producing the first communicating signal. A second mixer mixes the received second communicating signal with an oscillating signal to produce a mixed signal having a frequency corresponding to a function of the frequencies of the second communicating signal and the oscillating signal. In response to the second transmitting signal, the mixed signal is converted into a fixed signal with a constant frequency by a converter. A receiver receives the fixed signal.
