STL (7 GHz) / ISM (Lower 6 GHz) Diplexer

Model 18857

This diplexer allows broadcasters to run their licensed (lower 6 GHz) ISM band operations through the same antenna as their broadcast auxiliary services (STL). The model 18857 consists of a low band (5.925 - 6.425 GHz) for the ISM feed and a high band (6.875 - 7.125 GHz) for the STL feed resulting in superior isolation between the two feeds.

Reduces Costs Eliminates the need for a separate ISM antenna system. Eliminates the need for a separate STL (7 GHz) filter. Optimizes Performance No need to "patch-in" the ISM feed through the STL antenna via "lossy" circulator/filter assemblies. Robust IP Capability The licensed (lower 6 GHz) ISM band provides 4X more bandwidth than the unlicensed* (5.8 GHz) ISM band.
	Specifications: Passbands Low band: (5.925-6.425) GHz   High band: (6.875-7.125) GHz Passband Loss Low band: 0.75 dB [Typ.]   High band: 0.5 dB [Typ.] Passband Return Loss 20 dB [Min.] Power 5 Watts Mutual Isolation 40 dB [Min.] Interface CPR137F (All Ports)
Alternate flange/connector configurations are available upon request. * For unlicensed (5.8 GHz) ISM band applications see our model 16940 diplexer.
