Communication Components, Inc. Outdoor Combiner/Diplexer combines AWS and PCS band Basestation Tx/Rx onto a common feeder line.  Specifically intended for use in dual band systems, the outdoor diplexer DIP-1921A-O-AISG-1  facilitates the addition of new technollogies including LTE and new spectrum including AWS-3 to existing sites while providing a high degree of isolation between systems.  By reducing the number of feeder lines, the cost to upgrade a site (tower loading, leasing and installation costs) is significantly reduced.
The CCI Outdoor Combiner/Diplexer provides full band performance for each band with low insertion loss,  low Intermodulation, and  high power handling.  Excellent return loss delivers the best match to the antennas and base station, saving precious transmit power.  DC and AISG pass-through retains full RET and TMA capability utilizing CCI’s AISG suite of products.  Optional Dual unit with two Diplexers mounted on a single bracket is available.


Technical Description:

The Diplexer consists of multiple filters to combine (or divide) full band PCS and AWS signals.  This tower mount unit separates (or combines) both Tx and Rx signals of PCS and AWS onto separate DIN 7-16 connectors.  The fully weatherproof tower mount unit incorporates bypass circuitry which senses DC and AISG carrier frequency when presented to either port and automatically routes both to the antenna port.  The unit has internal lightning strike protection using a multi-stage surge protection circuit.
The filters have been designed to minimize Insertion Loss whilst maximizing isolation.  DIN Connectors are fully IP68 unmated.
