Introduction
This appendix describes the main signals paths for the different AR Standard Repeater
models.
CSel GSM Repeater
Figure A-1 CSel GSM Repeater Block Diagram
Figure A-1 illustrates a block diagram of a CSel repeater with four bi-directional channels.
This diagram is applicable to repeaters for the GSM, DCS, and PCS systems.
The signal from the base station is received via the repeater donor antenna and then
forwarded through a DC, used as an antenna port only if an RF modem is used. The signal
passes a DPX, is amplified in a LNA, and enters the CHEs which have two parallel channels
each. The first mixer stage on the CHE, which is controlled by a synthesizer, converts the
received frequency down to the IF frequency. The signal is then filtered by SAW bandpass
filters and amplified before it is fed to the second mixer stage for conversion back to the
original frequency.
