DIRECTIONAL COUPLERS

REV: 001, 04/18/02

• SPACE QUALIFIED

• 5 - 500 MHz DIRECTIONAL COUPLER

• FORWARD AND REVERSE COUPLING

TECHNICAL DESCRIPTION / APPLICATION

The CRF-20A-250 SQ Directional Coupler covers 5 - 500 MHz with a special luꢁped eleꢁent design to

reduce size, while ꢁaintaining high perforꢁance. Parts, ꢁaterials and processes are in accordance with

Merriꢁac docuꢁent CENG-0001, “Standard Design Requireꢁents for Space Qualified Devices”.
