AW 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 O 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 combiner filter QPX before it is fed to the wide band MS antenna which retransmits the signal at the same frequency to the aim areas http www redutelco com 2009 Redutelco All rights reserved Wide Tri Band Booster Model POTRP23 4 Product Features O High gain gt 70dB High output power 23dBm O Light weight small dimensions easy to install O Easy set DL UL gain via local PIN switch manually Gain adjustment of uplink and downlink gain adjust step is 1dB and the adjust scope is 30dB O Smart Automatic Level Control ALC to reduce interference to BTS O Linear power amplification to effectively suppress inter modulation and spurious emission O An alarm interface with unique color LEDs to indicate power supply and signal level of uplink and downlink O Simple installation with external AC DC adapter O Dual ports and full duplex design 5 Applications Example lt Donor Antenna Tall Repeater 5 Bars i EE gt 75dBm ERIP Loss2 Power Power uF Service Antenna RSSI Min Reception Signal Level Donor Antenna Gain 1 Input Power kaal Loss1 2 Output Power Input Pow
