CHANNEL-SELECTIVE REPEATER FOR MOBILE TELEPHONY

摘要

In a channel-selective repeater, signals are received from the receiver antennas in order to be selected and amplified in each of their own frequency channels. According to the invention, the amplified signals are led from the power amplifier (PA) of the channels via isolators and filters to each of their own antennas in an antenna arrangement. Preferably, the antennas are patch-antennas and the amplifiers built and connected via microstrip technology.
