The CH series resistors are used in many circuit configurations. The CH 100 Ω value is the ideal isolation resistor in Wilkinson power dividers used in millimeter-Wave phased array antenna applications like 5G base stations and small cells, satellite communications receivers, and RADAR. The CH 50 Ω value is the ideal termination to match circuit impedance to ground in virtually all millimeter-Wave applications up to 70 GHz. CH series resistors are also used in millimeter-Wave resistor networks to make broadband attenuators, power dividers, and directional couplers.
