UHF 400-470MHz Directional Coupler with N-female Connector is an RF passive device designed for isolating, separating, and combining signals. It accepts an input RF signal and divides it into two output signals.
UHF passive directional couplers are used to couple (divide) a portion of RF signals from a transmission line with a specific coupling factor. These couplers are constructed using two coupled transmission lines.
Directional couplers are specifically designed for use in Distributed Antenna Systems (DAS) to build chain UHF antenna systems for subways, tunnels, high-rise buildings, underground garages, and similar environments. The UHF Directional Coupler supports a wide frequency range of 400-470MHz and offers various coupling options, including 5dB, 6dB, 7dB, 10dB, 15dB, 20dB, 30dB, and 40dB.
