CSel CDMA/WCDMA Repeater AR Standard Repeater
A-2 044-05250 Rev A
The output signal from the mixer is then amplified in the PA and fed to a combiner which
combines the signals from the two channels on the CSA The output signal passes a CMB and
DPX before it is fed to the repeater service antenna.
CSel CDMA/WCDMA Repeater
Figure A-2 CSel CDMA/WCDMA Repeater Block Diagram
Figure A-2 illustrates a block diagram of a CSel CDMA or WCDMA repeater. The signal from
the base station is received via the repeater donor antenna and is forwarded through a DC,
used as antenna port only if an RF modem is used. The signal passes a DPX, is amplified in
a LNA, and enters the CSA which has two parallel channels.
The first mixer stage on the CSA, 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. The following amplifier on the CSA is controlled by the CU. The output gain can be
reduced to avoid instability due to poor antenna isolation by means of a gain control in the
CU. The gain control also affects other amplification stages. The output signal from the
amplifier is fed to a combiner which combines the signals from the two channels on the CSA.
The signal from the CSA is amplified on the PA and then fed to a DPX or, in high power
CDMA repeaters, to a BA. The amplified output signal passes the DPX before it is fed to the
repeater service antenna.
In high power CDMA or WCDMA repeaters, a BA boosts the output DL signal from the PA by
typically 6dB. The amplified signal is fed to the DPX at the service port. Only the DL path has
a BA which is powerwed by a second PSU.
