1 Description
The wide dual band booster (PODRP27) is a bi-directional amplifier used to
enhance signals between a mobile and a base
station. This repeater type is used for digital
telecommunication system:
1) -It picks up the strongest signal from
BTS via the Donor Antenna,
2) -Linearly amplifies the signal and then retransmits it via the Indoor
Signal Distribution System to the weak/blind coverage area.
3) -And the mobile signal is also amplified and retransmitted to the BTS
via the opposite direction.
It is commonly used in the area there are two type of mobile network, such as
GSM/CDMA, GSM/DCS, and GSM/UMTS. It will reduce site deployment cost
by using one dual band donor antenna, one dual band service antenna, and
dual band repeaters in one enclosure.
It is applied to small, medium-size areas such as corporation office, shop mall,
bus station, factory etc.
This model booster is commonly used in situations where large numbers of
frequency carriers are to be repeated or when base station synthesized
frequency hopping is used.
This model booster does not separate out specific carriers but amplify and

retransmit all signals within a defined frequency band. Inter-modulation
distortion caused by band selective repeaters usually means that lower output
power per carrier can be realized compared to channel selective repeaters.

The RF link (donor) towards the base station is typically fed from an
outdoor antenna while the coverage area is fed by an indoor antenna
 The signal from the base station is received via the Dual band Donor
antenna, then forwarded through a Quad filter (QPX), is amplified in a
low noise amplifier (LNA), and enters the band selective amplifier
board (BSA).
 The first mixer stage on the BSA amplifier board, which is controlled by
a synthesizer, converts the received frequency down to the IF
frequency. The signal is then filtered by an IF 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 output signal from the mixer is then amplified in the power
amplifier, which is controlled by the CU(Control Unit board).The output
signal passes a Quad filter (QPX), before it is fed to the Dual band
MS antenna which retransmits the signal at the same frequency to the
aim areas.
