The C1-C98 models are a series of couplers from 6-30dB with upper frequency performance to 4200MHz, with low PIM high power, and 4.3-10 , 7-16DIN, or Type N connectors. The unique tapered stripline coupler with large ground plane spacing and large conductors is suitable for power levels to 200Watts which puts it in a category of its own for high power in stripline. Connectors are flange mounted and factory only interchangeable for rapid manufacturing with minimum inventory. All units are completely sealed and suitable for outdoor or other hostile environments.
