Service : Bespoke RF & Microwave Filter Design up to 1GHz for Defence, Emergency Services and Commerce

With more than 30 years experience in the design and manufacture of bespoke RF and Microwave filters we focus on frequencies below 1 GHz. We design and supply lowpass, highpass, bandpass, bandstop, notch and diplexer/multiplexer filters. Options include amplitude / phase / delay correction or pre-distortion.

Many of our filters use low-loss Coaxial Ceramic Resonator technology. Inherently this technology gives small size and light weight with good temperature stability and NVH / rugged environmental performance.

LEN also has extensive experience in the design and manufacture of Broadcast Analogue and Digital Video products. Many broadband satellite links such as video use our ceramic bandpass filters in their IF stages.

Our bespoke RF & Microwave products are extensively used in military, emergency services and commercial applications.

Recent projects include:

• Supplying hundreds of Notch Filters to UK Police Forces, to cure an interference problem from a new Radio Paging band.
• Supplying 650 identical BPF with phase equalisation for the ASTRON Radio Telescope project antenna array.
• Supplying diplexers to replace seperate Transmit/Receive filter pin diode switching.
• Supplying bandpass filters for a fast spinning Radar head used in short range radar for ship to oil rig docking in rough weather.
