DDCH-50-521+

DC Pass, High Power Dual-Directional Coupler, 50Ω, 50dB Coupling, 300W, 20 to 520 MHz

Mini-Circuits DDCH-50-521+ high-power dual-directional coupler provides high power handling up to 300W and insertion loss of 0.07 dB Typ with 50 dB coupling. Covering frequencies from 20 to 520 MHz, it supports a wide variety of applications from military 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 full frequency range. The coupler is designed into an open printed laminate (1.0 x 1.5 x 0.128”) with wrap-around terminations for good solderability and easy visual inspection.

Features

• high power, up to 300W • low insertion loss, 0.07 dB Typ. • excellent in/out return loss, 35 dB typ • high directivity, 21 dB Typ. • DC current pass through input to output
