GPS Dual Triplexer Picture

GPS Dual-Triplexer (L1, L2 and L5 Channels)

This fully-Mil, highly ruggedized assembly is a GPS triple channel dual triplexer. There are three evanescent mode bandpass filters connected together at input and output. The bandpass filters tune the L1, L2 and L5 GPS channels. Two of the bandpass filters are provided with internal cross coupling so as to achieve sharp rejection near their passbands, and thus display at least 20 dB isolation to the adjacent GPS channel. The assembly thus provides passbands for the L1, L2 and L5 GPS frequencies, rejecting all other frequencies in accordance with the specifications tabulated below.
