Bandpass/bandstop (BP/BS) and lowpass/highpass (LP/HP) diplexers meeting rigid Passive Intermodulation (PIM) specifications are the essential building blocks of innovative testing system architectures. By integrating these filters with Dow-Key's switch matrices, an OEM can construct a single automated test system capable of covering a variety of frequency bands. Test systems of this kind can be further expanded to accommodate injection of interfering signals, monitoring ports and other customer requirements.
