1. Introduction

Repeaters are used to fill out uncovered areas in cellular mobile systems, such as base
station fringe areas, road tunnels, business and industrial buildings, etc.
A repeater receives signals from a base station, amplifies and retransmits the signals
to mobile stations. Also it receives, amplifies and retransmits signals in the opposite
direction. Both directions are served simultaneously.
To be able to receive and transmit signals in both directions, the repeater is connected
to a donor antenna directed towards the base station and to a service antenna directed
towards the area to be covered.

Longent dual-band selective repeaters with 2 adjustable bandwidths have filters that

can be set to various bandwidths. This repeater type is suitable for the most carriers that need
2 band blocks support in 800 MHz cellular band.

The signal from the base station is received via the repeater donor (BS) antenna and is
then forwarded through a directional coupler (DC). The signal passes a duplex filter
(DPX), is amplified in a low noise amplifier (LNA), and enters the band selective
amplifier (BSA), which has two parallel bands.

The first mixer stage on the BSA amplifier, which is controlled by a synthesizer,
converts the received frequency down to the IF frequency. The signal is then filtered
by a SAW band pass filter and amplified before it is fed to the second mixer stage,
controlled by the same synthesizer as the previous one, for converting back to the
original frequency. The SAW filter can be adjustable for each BSA has adjustable
bandwidth.

A detector on the PA measures continuously the output level. The signal from this
detector is used by the automatic level control, ALC, to supervise and, if necessary,
reduce the output power to keep it under a setting level.

The output signal passes duplex filter (DPX) and fed to the repeater service (MS)
antenna.

The uplink signal path, i.e. from the mobile station through the repeater to the base
station, is identical to the downlink path the other way round. Only some levels and
component values differ.
