25 years ago to the day Link Microtek opened its doors for business. We know we wouldn’t have reached this major milestone without our fantastic customer base, suppliers, professional service providers and hardworking staff so a sincere thank you to everyone involved on the journey over the last 25 years.
Whilst so many people much closer to the sharp end in these troubled times are doing much more we're proud to have helped in a small way. We routinely supply telecoms products like antennas and various components to the MNOs and their sub-contractors and it's good to know that our products are being used to provide the necessary extra coverage at Nightingale hospitals in London, Harrogate & Birmingham. Our thanks go to the NHS and emergency services for putting themselves at risk to help us all.
We recently had an article published in CBNW Xplosive magazine discussing the merits of real time spectrum analysis (RTSA) and the important specifications behind radio direction finding (DF). The important message is that not all analysers are equal. Specifications even from well known test equipment manufacturers can give rise to complacency that all is well when in actual fact the displayed average noise level (DANL) is prohibiting finding low level signals or costing miles in terms of detection range.

Our new miniature single-channel coaxial rotary joint features a wide operating frequency range of DC to 40GHz, making it suitable for a variety of test applications. Specifically, it would be ideal for EMC evaluation of 5G systems as well as performance assessment of antennas for say radar systems at the lower-frequency end and Ka-band satellite communications systems at the higher end. The AMCORJ-WB2 rotary joint is of a sliding-contact design, which provides the inherent advantages of low insertion loss and good VSWR performance over a wide frequency range.
The new AM90CD-LP miniature narrowband dual-loop coupler enables designers to incorporate forward and reverse power monitoring in military or commercial microwave systems that are subject to tight space constraints. With flange dimensions of 41.5 x 41.5mm and a waveguide length of just 33.6mm, the device is an ideal alternative to much larger conventional broadband couplers.
The latest addition to our comprehensive range of microwave rotary joints is the AMCORJD-2KU device, which offers a coaxial dual-channel Ku-band capability that makes it ideal for both satellite-on-the-move and radar applications, either military or commercial. While microwave rotary joints of this type are usually designed with a high-frequency transmit channel and a lower-frequency L-band receive channel, the new device features two channels operating in the Ku band. Minimising crosstalk is therefore a critical consideration, and the rotary joint achieves an impressive 50dB minimum isolation between the channels with typical figures being better than 70dB.
Designed and fabricated in house for use in Ku-band mobile satellite-communications antenna systems the assembly incorporates a feed arm, transmit and receive filters, a rotary joint and an orthomode transducer (OMT). In addition to satisfying the tight space constraints imposed by the compact nature of the antenna system, the feed assembly had to achieve strict performance criteria regarding low transmission losses and cross polarisation, as well as high isolation between transmit and receive channels.
We now supply the comprehensive range of coaxial and waveguide phase shifters manufactured by Narda-ATM. Covering microwave frequency bands all the way up to 40GHz, the phase shifters come in both coaxial and waveguide styles and can be specified with digital counting dial, direct reading dial and servo motor control options. A number of models are specifically designed for use in Ka-band systems. Ideal for adjusting the phases of elements within a phased array antenna system, the devices are primarily aimed at military or commercial radar applications and can also be used for drive feed balancing on high power amplifiers, as well as general test-and-measurement applications.
The main focus for us on the stand at this year’s DSEI exhibition will be the Azdec optical MLC (mobile local communications) system, which offers a totally secure, non-RF, cable-free voice comms solution for a wide variety of defence-related applications. Originally developed using infra-red technology to provide secure bridge communications on board naval vessels, the Azdec system has now been adopted in other military scenarios where radio-frequency transmissions might jeopardise security.
