Dual-directional coupler

13 September 2017 Telecoms, Datacoms, Wireless, IoT

Mini-Circuits announced the release of its latest high-power SMD high-power coupler. The DDCH-50-521+ dual-directional coupler provides high power handling up to 300 W and insertion loss of 0,07 dB typical with 50 dB coupling. Covering frequencies from 20 to 520 MHz, it supports a wide variety of applications from military communications systems to commercial, including GSM transmitters and more. High directivity of 21 dB provides accurate sampling from the coupled port, and typical input/output return loss of 35 dB provides excellent matching over the full frequency range. The coupler is designed into an open printed laminate (2,54 x 3,81 x 0,325 cm) with wraparound terminations for good solderability and easy visual inspection.
