About ELCO STAR Ltd.
ELCO STAR Ltd. was founded in 1990 by five members of the Bulgarian Academy of Sciences. It is 100% private company. The initial idea was to be involved mainly in R&D and OEM. Soon we realised that we should have some mass production items to be able to survive on the Bulgarian market, which at that time was, and still is hardly available, let alone competitive.
We started manufacturing receivers for TV satellite reception, which were very successful. At that time we rented a production facility in Sofia where we could produce about 4.5 thousand square feet of PCBs per year.
Since the foundation of the company more than 10 years ago we have worked on projects in various fields of the electronic industry such as:
* microprocessor controlled microwave appliances - mainly receiving equipment for frequency bands between 1 GHz, and 40 GHz, including synthesised LNB's
* a wide variety of RF and microwave components - VCO's, amplifiers - both wideband, and narrowband, mixers, DRO's, surge arresters, YIG devices, splitters, power dividers, multipliers and others.
* radiometric appliances - for measuring the radio temperature in the 10GHz band
* microwave moisture meters - for measuring the moisture content of various types of grain
* an all digital satellite receiver for analogue signals based on DSP technology - in close cooperation with ITT - Intermetall Freiburg
* cable distribution main stations for CATV/MATV - receivers, and modulators for analogue signals as well as converters for electrical to optical signals.
* GPS antennas, and electronics for fleet management
* patch, grid, logoperiodic, and PCB antennas for various purposes - GPS, GSM, spread spectrum ISM band, etc.
* smart cards with secure microprocessors from Atmel for access systems
* microwave (10 GHz) identification systems for railway carriages, as well as for tracking other mobile elements, such as cars, carts, etc., for speeds up to 160 km/h and distances from 1 to 10 meters. These systems are very suitable for car anti theft applications.
* microwave fencing systems for guarding and protection of large open areas
* digital modems for analogue relay networks
