Exceed Microwave has enhanced their ISO-W-12500-5000-75 which is a WR75 Full Band Isolator with excellent return loss and isolation across the entire passband. It also has very low insertion loss of <0.2 dB.
Exceed Microwave’s WZ-Series Band-pass Filters utilize super high Q resonators, providing very low insertion loss while maintaining high selectivity. Low insertion loss and the structural design allows for higher power handling than any other waveguide filter.
Exceed Microwave’s WC-Series waveguide diplexers can provide very wide pass-bands and also comes in small sizes. DPX-WC-22-28-34 is a WR34 diplexer covering nearly the entire waveguide operating frequency band.
