DSEi 2021 Infrared comms

DSEi 2021 logo

We're pleased to announce that we are exhibiting at DSEi 2021, stand H2-508. Our main focus is our unique Azdec infrared voice communication system that provides local mobile communications in areas such as operation rooms, secure training facilities, machinery spaces, ships' bridges and bridge wings. The system has no detectable RF emissions satisfying TEMPEST or EMCON conditions and is immune to electrical noise thus providing clear audio in demanding environments. Our Azdec systems are 100% designed and manufactured in the UK.

Also on display will be the SignalShark radio monitoring and direction finding (DF) system manufactured by Narda Safety Test Solutions. The SignalShark family includes handheld and remote units providing fixed, vehicle mounted or man portable solutions and coupled with the automatic detection finding antenna (ADFA) the system is capable of automatically providing signal bearings and a local 'heatmap' for the source of unwanted emissions. Superior RF performance means that low level field strengths are captured from further away and fast intermittent signals can be captured and identified even when masked by other signals operating at the same frequency.

We're back in the office Monday 4th January 2021

What a year 2020 has been!

As Christmas approaches we reflect on a difficult year for everyone.

We would like to thank all our customers and suppliers for their continued support and hope you have a safe and enjoyable Christmas.

2020 marked our 25th year in business but clearly our anniversary plans were shelved. Instead we have made a donation to a local charity in Basingstoke supporting homeless or vulnerable people.

Here's hoping that 2021 is an altogether better year.

We re-open for business on Monday 4th January 2021.

Link Microtek products used at Nightingale hospitals

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.

SignalShark RTSA magazine article

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. Download the article here.

Miniature coaxial rotary joint offers wideband capability for 5G test applications

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.

Dual-channel Ku-band rotary joint ideal for satellite on the move and radar applications

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.
