Castle Microwave is pleased to represent a UK company that has established a reputation for delivering reliable power amplifiers and filter products for a wide range of commercial and military applications worldwide.
With a catalogue of standard products and the capability to develop custom solutions, SARAS offer linear and ultra-linear power amplifiers for use in applications including Tactical Communications and Surveillance, Broadcast and Digital RF and Microwave communication equipment using digital modulation schemes. Amplifier capabilities include:
Fast rise times
Options for integrated filters, controls, or other requirements.
SARAS utilises a range of technologies to realise compact and cost-effective filtering solution. A large range of filter designs are currently available:
Lumped Element – compact Size, Surface/PCB mount or connectorized, wide range of topologies, with designs to 3GHz and above
Tubular – high-power handling capability, high rejection and broad stopbands make this technology ideal for harmonic rejection.
Ceramic – typically used for frequencies between 200MHz and 8GHz, using high dielectric ceramic resonators these filters offer low insertion loss, low cost, and small size.
Cavity – available in Machined Combline and Interdigital designs, cavity filters can offer high power handling, low loss and high levels of rejection
Waveguide – available from 1GHz upwards, SARAS waveguide filters provide high-power handling and low insertion loss
Microstrip and Suspended Substrate – using printed circuit technology that is suitable for both broadband and narrowband filters from 500MHz to 40GHz. Advantages include compact Design, high reliability and repeatability
All of the above products are designed and manufactured in the UK, contact us today to discuss your requirements!
