Coaxial Couplers,

90° Hybrid 3dB Directional

ATM manufactures a variety of 90° Hybrid 3dB directional couplers. For more information feel free to call us and discuss your needs with one of our design engineers.

The Hybrid Directional Coupler splits power equally between its two output ports.
Two output ports are 90° out of phase with each other.
Construction is stripline in an aluminum housing.

GENERAL SPECIFICATIONS
OCTAVE RF POWER:	50 watt average 3kw peak
BROADBAND RF POWER:	30 watt average 2kw peak
PHASE BALANCE:	Typically: +/-5°
RF CONN:	SMA Female or Type N Female- 4 ports
