Mini-Circuits ZABDC20-232H+ is a 20-dB bi-directional coupler ideal for power leveling and monitoring
L-band applications. The rugged aluminum alloy case measures 2.0” x 2.0” x 0.88” high, with gold-plated
SMA or N-type connectors.
Key Features
Feature
Mainline loss 0.25 dB typ.
Advantages
Extremely low mainline loss for applications where signal strength is key, such as GPS,
CDMA, UMTS, and LTE base station transmitters
Enables more accurate sampling for VSWR measurements
Allows flexible deployment between active components and their DC power supplies
Pass through at 10 MHz supports reference clock frequency communication to remote
systems
Extended frequency range makes this coupler ideal for use in satcom systems, such as
LNB/BUC installations
Directivity 23 dB typ.
DC pass through 2.0 A max.
10 MHz pass through
Full L band coverage
