Over 130 new additions to the range of standard waveguide products manufactured by Narda Microwave are now available in the UK from Link Microtek, the specialist supplier of RF and microwave components and subsystems. The new products include waveguide-to-coaxial adapters, cross-guide directional couplers, gain horns and terminations, all of which are produced in accordance with the quality assurance programme of Narda’s parent company, L-3 Communications.
The adapters cover frequencies from 1.7 to 40.0GHz and feature a choice of SMA, 2.92mm or Type N connectors. Both right-angle and end-launch styles are offered, and all variants have a maximum VSWR of 1.25:1.
The new cross-guide directional couplers are available with either SMA connectors for applications in the frequency range 7.05 to 40.00GHz or Type N connectors for frequencies from 2.6 to 15.0GHz. All models feature a coupling value of 30dB, a minimum directivity of 20dB and a maximum frequency sensitivity of +/- 1dB.
A comprehensive line-up of standard horns offers 10, 15 or 20dB gain values for frequencies ranging from 1.7 to 40.0GHz. In addition, two wideband models cover the frequency bands 7.5 to 18.0GHz and 18.0 to 40.0GHz and can be specified with or without adapters.
Completing the expanded Narda range is a family of low-power and medium-power rectangular waveguide terminations. The low-power models span frequencies from 1.7 to 40.0GHz and offer a maximum VSWR of 1.04:1, while the medium-power versions are available over the frequency range 2.6 to 40.0GHz with a maximum VSWR of 1.15:1.
