RFS Introduces High-Power 3dB Coupler for Transmitter and Channel Combining in the UHF TV Band

RFS has introduced its new high-power 3dB directional coupler for use in the UHF TV band for transmitter and channel combining. The RFS DC618E-HP, rated for 80kW-120kW depending on application at UHF frequencies 470-700MHz, is the latest addition to RFS’ family of directional couplers and will change the landscape for balanced combining applications.
