Abstract
A repeater for transmitting and receiving radio frequency (RF) signals to and from a pager. The repeater includes a forward path for receiving a first RF signal from a base station and a reverse path for receiving a pager signal from a pager. The forward path includes a channelizer which down converts the first RF signal to an intermediate frequency (IF) signal, amplifies the IF signal, and up converts the IF signal to a second RF signal suitable for transmission to a pager. The reverse path includes a second amplifier which amplifies the pager signal to an amplified signal suitable for transmission to a base station antenna.
