For the system noise temperature calibration of the K/Q/W triple-band cryogenic receiver on Tianma Radio Telescope (TMRT), a design of W-band eight-hole waveguide directional coupler is proposed in ...

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 ...

Abstract: This study presents the design and characterization of a directional coupler for applications in the 3 GHz frequency band, implemented using microstrip technology. Directional couplers are ...

You picked up an RF directional coupler in the lab, but the ports are not labeled. What are the typical 4 ports of an RF directional coupler?

The Model IPP-3013 is a dual-directional 200-W coupler covering 100 to 1000 MHz in a 1.50- by 2.50-in. package with SMA connectors. A typical application for the coupler includes monitoring forward or ...

KRYTAR, Inc., a developer of ultra-broadband microwave components and test equipment, announces a new directional coupler operating in the wideband frequency range of 0.5 to 26.5 GHz (L- through ...

Abstract: In this letter, a W-band power combiner is proposed by exploiting the 3-dB branching waveguide directional couplers and GaN power amplifiers. In the framework, a novel waveguide coupler is ...

I am not sure if this is the right place to ask, but I wouldn't know where else to go. I participated in the edX course at the end of 2024 and I would like to use the upcoming production run to ...
