General Info
Up to 110 GHz
SHF’s microwave components are broadband devices suitable up to 110 GHz.
More than Bias Tees and DC Blocks
Our SHF BIAS TEES are well known but perhaps a slight variation does suit your application even better. 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 out of 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. Based on our air line construction, these passive components provide resonance-free transmission over the entire operating range.
The SHF ATT110 A precision fixed ATTENUATOR is available in a wide variety of different connector and attenuation combinations.
Our broadband resistive POWER DIVIDERS split a signal into two equal parts, or combine two signals. They have 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 to compensate for distortion caused by the lack of bandwidth of a DUT (e.g. a RF cable assembly).
