The appearance of a new communication standard CDMA-450 in the mobile communication systems has demanded from the operators of NMT-450 to release a part of antenna-feeder channel for implementation new projects. The application of DPS2-12U in the base stands (RS 4000) of the standard NMT-450 makes it possible to empty 1 antenna-feeder channel.
At the present moment the duplexer has a peak carrying capacity around 700 Wt what corresponds to the simultaneous operation of 8 channels of NMT-450. The next project - the modification of this product for providing larger carrying capacity.
