UHF Loop Coupler
UBS designs and manufactures a variety of directional couplers optimized for accurate power measurements in air-line coaxial transmission lines. The series of UHF couplers covers all DTV channels from 470 MHz to 860 MHz. They are ideally suited for DTV and wireless applications by virtue of their high power capability, lowest insertion loss, high directivity and excellent matching with the prime line. The available from stock couplers include models to cover the entire frequency range of 470 MHz to 860 MHz, and as well as specialized models perfected for a particular set of DTV channels. These models are available in a single-probe configuration (for monitoring the power flow in one direction) and a dual-probe configuration (for sampling both incident and reflected power), for the standard coupling values of 30 dB, 40 dB and 50 dB.
