Product Overview
Mini-Circuits BDCH-25-33+ high-power bi-directional coupler provides high power handling up to 150W
and low insertion loss of 0.2 dB. Covering frequencies from 800 to 3000 MHz, it supports a wide variety
of applications from power amplifiers and antenna feeds to various digital communications and more. High
directivity of 28 dB provides accurate sampling from the coupled port, and 31 dB return loss provides excellent
matching over full frequency range. The coupler is designed into an open printed laminate (1.00 x 0.50 x
0.051”) with wrap-around terminations for good solderability and easy visual inspection.
Key Features
Feature
Advantages
High power handling:
150W @ 85°C
90W @ 105°C
Usable in many systems with high-power requirements such as
antenna feeds, power amplifiers, and others that require sampling a
high power RF signal.
Used primarily in high power transmission applications, the excellent
through-path signal loss maximizes the power transmitted to the
antenna.
Low insertion loss, 0.2 dB
Flat coupling values across the frequency range allows accurate signal
sampling through the coupled port with minimal measurement error.
Good coupling flatness, ±0.6 dB
Good directivity allows accurate signal sampling through the coupled
port with minimal measurement error
High directivity, 28 dB
Provides good matching for 50Ω systems.
Excellent return loss, 31 dB
