DC Pass, High Power Bi-Directional Coupler 50Ω 35dB Coupling 150W 700 to 2700 MHz BDCH-35-272 The Big Deal • High power handling, up to 150W • Low insertion loss, 0.2 dB Typ • Good return loss, 23 dB Typ (all ports) CASE STYLE: PQ2098 Product Overview Mini-Circuits BDCH-35-272 high-power bi-directional coupler provides high power handling up to 150W and insertion loss of 0.2 dB Typ. Covering frequencies from 700 to 2700 MHz, it supports a wide variety of applications from military to various cellular base station applications and more. Excellent return loss at all ports of 23 dB typical provides superb matching over the full frequency range. The coupler is designed into an open printed laminate (0.5 x 1.0 x 0.051”) with wrap-around terminations for good solderability and easy visual inspection. Key Features Feature Low insertion loss, 0.2 dB typ. High power handling, up to 150W Advantages Used primarily in high power transmission applications, the excellent through-path signal loss maximizes the power transmitted to the antenna. Usable in many systems with high-power requirements such as antenna feeds, power amplifiers, and others that require sampling a high power RF signal. Good return loss, 23 dB typ. (all ports) Provides excellent matching for 50Ω systems. Good Coupling flatness (±1.1 dB typ) Flat coupling values across the frequency range allows accurate signal sampling through the coupled port with minimal measurement error. DC current passing up to 2.5 A Suitable for use in systems requiring DC voltage on the RF line, such as supplying bias to remote circuit via the antenna cable.
