Our modern Design Facillities can prototype, and manufacture to your requirements from 10 Khz to 3Ghz to meet your specific needs from milliwatts to Kilowatts using the latest Themionic Valve Technology or Solid state Technology.

Customers and end users have included UK Defence Research Agency, Racal Avionics, BAE Systems, JET Fusion Reactor, EF Johnson, Ericsson, Vodafone, Motorola Mobile Radio, Decibel Mobilcom, Siemens Communications Systems, Isomet. Some customers require designs which they then produce, others provide a prototype which is turned into production units and manufactured for them, and others require a full design and build. Much of the work is covered by non-disclosure agreements which prevent details being given as examples.

 100W mobile radio base station designed and prepared for customer production. Approx. 2500 units in service.

  Ultra linear UHF amplifiers to carry trunked radio signals underground in the Tyne & Wear Metro (a subway system in Newcastle, England). 26 amplifiers were installed in 1991/2, each operating at 150W dissipation ‘24/7’ since then. They have accumulated well over 3million operating hours, and earlier this year we had the first and only field failure.

  Ultra linear bi-directional, high gain, amplifiers for extending 800MHz trunked radio communications into blast proof bunkers at oil refineries. Andrews, Decibel and others all carried such products in their catalogues, but could not deliver in practice. Eltac designed and delivered units in a matter of weeks.

 Compact 50 and 100W 500-1000MHz amplifiers for jamming applications. These products have been in continuous production since 1990.

 1.5kW sources at 13.56MHz and 27.12MHz for industrial plasma generators and laser excitation. 

• High power harmonic filters and directional couplers to solve specific installation problems at co-located base station sites. Several hundred filters were subsequently produced. 

Single channel filtered on-frequency repeaters with controlled delay and group delay for carrying paging signals into ‘dead’ areas.
