Marki Microwave RF/microwave surface mount triplexers route signals by frequency into three frequency bands, offering broad coverage, low insertion loss, high out-of-band rejection, and strong channel-to-channel isolation. Their resonance-free response makes them well-suited for multi-band transceivers, satellite payloads, and frequency channelization in test and measurement systems, replacing arrays of discrete filters and combiners with a single integrated solution.
