Point-to-multipoint communication terminal having a single RF chain
First Claim
1. A communication terminal, comprising:
- first and second antennas, for respectively communicating with first and second remote terminals;
a single up-converter, which is arranged to up-convert an input signal to produce an RF transmit signal; and
a switching circuit, which is arranged to couple the single up-converter to the first antenna in order to transmit the RF transmit signal to the first remote terminal during first time intervals, and to couple the single up-converter to the second antenna in order to transmit the RF transmit signal to the second remote terminal during second time intervals, which do not overlap the first time intervals.

Abstract
A communication terminal includes first and second antennas for respectively communicating with first and second remote terminals and a single up-converter that is arranged to up-convert an input signal to produce an RF transmit signal. The communication terminal further includes a switching circuit, which is arranged to couple the single up-converter to the first antenna in order to transmit the RF transmit signal to the first remote terminal during first time intervals, and to couple the single up-converter to the second antenna in order to transmit the RF transmit signal to the second remote terminal during second time intervals, which do not overlap the first time intervals.

10. A method for communication, comprising:
-
producing an input signal for communicating with first and second remote terminals via respective first and second antennas; up-converting the input signal using a single up-converter to produce a Radio Frequency (RF) transmit signal; coupling the single up-converter to the first antenna in order to transmit the RF transmit signal to the first remote terminal during first time intervals; and coupling the single up-converter to the second antenna in order to transmit the RF transmit signal to the second remote terminal during second time intervals, which do not overlap the first time intervals. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
