Diplexers/Duplexers

PRODUCTS AND SERVICES

This diplexer uses TE Mode waveguide puck resonators to achieve narrowband filters of less than 0.25% bandwidth yet still provide a pass band loss on the order of < 1.5 dB. In addition to the low loss provided by the high Q ceramic resonators, cross coupling is used to achieve very deep rejection of 75 dBc at a 4:1 shape factor. This device also incorporates a sampling coupler and is available in both diplexer and double band pass configurations in frequency ranges of 2250 MHz to 2800 MHz...

The CMIMUX3-90DB-03A is a cavity triplexer that operates within the L-band, S-band, and C-band frequencies. The triplexer is designed in a very compact size and with a bulkhead “N” connector for easy mounting to a bulkhead.

Microlab/FXR, a wholly owned subsidiary of Wireless Telecom Group, Inc., provides a low cost Diplexer, to separate or combine all the cellular wireless frequency bands from the WiMAX and WiFi bands above 3 GHz.

The 11DCR8C-898/943/C40-D is a very high-performance EGSM diplexer in a drop-in package. The high-Q ceramic and double cross-coupled design achieves a high level of selectivity and channel isolation while maintaining excellent passband characteristics in applications where the frequencies of the channels are very close. Measuring approximately 3.5” long by 0.33” wide by 0.641” high this mass-producible diplexer can give you an edge in your high-performance application...
