This essential measurement accessory for microwaves has morphed from waveguides down to tiny surface-mount components. Part 1 examines the need for and basic principles of directional couplers and ...

Abstract: A class of wideband directional couplers suitable for achieving different coupling levels are proposed in this paper. The proposed couplers have been implemented using the double-layer ...

Ultra-broadband microwave components and test equipment developer KRYTAR, Inc. announces a new directional coupler operating in the wideband frequency range of 1.0 GHz to 26.5 GHz offering nominal ...

SUNNYVALE, CA. KRYTAR Inc. has announced a new directional coupler operating in the frequency range of 6.0 to 40.0 GHz, offering nominal coupling of 20 dB in a compact package. KRYTAR’s new ...

A directional coupler is used to sample a small amount of input signal power for measurement purposes. Port 1 is the input port; port 2 is the output port; port 3 is the coupled port; port 4 is the ...

Krytar’s Model 1100110010 directional coupler maintains a flat nominal coupling of 10 dB (±1.5) from 10 GHz to 90 GHz and 10 dB (±1.8) from 90 GHz to 110 GHz. Aimed at wireless designs and test and ...

Abstract: A novel design for a microstrip wideband directional coupler is proposed by using fragment-type structures. The use of a fragment-type structure may provide satisfactory flexibility and ...

THEORY: A Directional Coupler is a passive microwave component used to sample or divide the input signal in a predetermined direction. It is a four-port network in which power entering one port is ...
