Passive Microwave Modules

Up to 110 GHz

SHF’s microwave components are broadband devices suitable up to 110 GHz. Based on our air line construction, these passive components offer resonance-free transmission over the whole operating range.

More than Bias Tees and DC Blocks

Our SHF Bias Tees are well known but maybe a slight variation does fit even better to your application. DIPLEXERS are bias tees with a certain bandwidth in the low frequency path to combine or separate high frequency and low frequency signals into or from a single line. DC-FEEDERS are bias tees without the capacitor. Therefore it provides slightly lower insertion loss in case it is connected to an AC-coupled device which already has a capacitor on its input.

Some modules need a 50 Ohm path to ground so that a current can flow. This ground path is provided by our DC-RETURNS.

Our broadband POWER DIVIDER splits a signal into two equal parts, or combines two signals. It has a characteristic impedance of 50 ohms when the output ports are terminated with 50 ohm loads.

A typical application for a Broadband Linear Equalization Filter is the compensation of distortions caused by the lack of bandwidth of a DUT (e.g. a RF cable assembly).
