LDDC-12.4/18-30S 30 DB Dual Directional Coupler
| Leader-mw | Introduction to 30dB Couplers |
Introducing the LEADER-MW bidirectional coupler, the perfect solution for monitoring power and ensuring accurate measurements in a variety of applications. These innovative 4-port couplers combine the functionality of two 3-port couplers to easily monitor forward and reflected power.
The bidirectional design of the LEADER-MW bidirectional coupler is achieved by cascading the main lines of two 3-port couplers, thereby integrating two back-to-back couplers in the same package. This unique design enables excellent performance in directionality, flatness and coupling accuracy, making it ideal for a variety of professional applications.
One of the main features of the LEADER-MW bidirectional coupler is its versatility of application. From power sampling and measurement to amplifier levels, VSWR monitoring, field control, and amplifier and load protection, these couplers are designed to meet the diverse needs of professionals in a variety of industries.
