Band reject duplexers

19 October 2005 Telecoms, Datacoms, Wireless, IoT

RF Cable & Connector Supplies has added a comprehensive range of band reject duplexers to its range of radio communications support products.

These duplexers are available in all of the current commercial radio communications bands - 66/88 MHz, 138/174 MHz and 380/470 MHz. A minimum frequency spacing of 3,5 MHz is usable in both the 66/88 MHz and 138/174 MHz units, and 5 MHz in respect of the UHF variant. Quarter wave resonators are utilised on the UHF variant, with helical units on mid and high-band versions.

All units have a continuous power rating of 80 W with an intermittent rating (40% duty cycle) of 100 W. Return loss figures of over 14 dB are easily achieved on all units. Standard terminations are 'N-type' female.
