Product Overview
Mini-Circuits MBDA-30-451HP high-power bi-directional coupler provides high power handling up to 200W and
mainline loss of 0.15 dB. Covering frequencies from 225 to 450 MHz, it supports a wide variety of applications
from power amplifiers and antenna feeds to military applications and more. High directivity of 28 dB provides
accurate sampling from the coupled port, and 30 dB typical input/output return loss provides excellent
matching over full frequency range. The coupler is fabricated using laminated PCB process (1.0 x 1.0 x 0.051”)
and includes wrap-around terminations for good solderability and easy visual inspection.
