First-responder radio system specialists

Filtronic is a thought leader, innovator and problem solver in the mission-critical communications sector, helping to overcome complex RF challenges such as combining, filtering, and mitigating dynamic interference. We have established an enviable reputation in critical communications, most notably serving the US Project 25 (P25) public safety market with high-performance ceramic filter/combiners and RF conditioning products.

Public safety mission-critical communications

Public safety communications via LTE networks

We continue to apply our intimate knowledge of the telecommunication infrastructure market to create advanced products for public safety LTE-based communications. These support the speed and data requirements of new technologies used by the emergency services, such as body-worn cameras, drones and automated vehicles. For example enabling mission-critical voice communications to continue over LMR public safety networks, while non-critical data communications are carried over commercial-grade LTE networks.

Land Mobile Radio expertise with an enviable track record

For > 30 years we have supported Land Mobile Radio (LMR) networks with innovations across the RF spectrum. Filtronic specialise in high-performance tower top amplifiers, filters, crossband/in-band combiners, power amplifiers, as well as a range of customised solutions for leading OEM’s.  Our brand name is synonymous with quality and performance within the critical communications markets. Our clients view our products as being the gold standard and see Filtronic as the go to partner for LMR applications in 700MHz, 800MHz and 900MHz.

5G – Next generation critical communications solutions for a converged network

Filtronic is well placed to support the public safety market as it develops hybrid solutions, with mission-critical voice communications continuing over LMR public-safety networks, while non-critical data communications are carried over 5G networks. We are specialists in interference mitigation to improve radio communication performance and clarity.  Filtronic has a range of products that are applied within a converged network including transceivers, power amplifiers and multiplexers.

Critical communications - products

Tower top amplifiers

Filtronic’s Tower Top Amplifiers (TTAs) feature smart redundancy, which continuously monitors the health of the balanced quadrature-coupled amplifiers. In the case of a failure in one of the amplifiers, the system can continue to operate using the redundant amplifier. If both amplifiers are lost the system will function in...

Custom combiners

Filtronic offers a range of custom combiner products for both in-band and cross-band applications. An RF combiner acts as a transmission component, combining the power between two or more ports. Our expertise lies in highly complex applications, such as combiners with a very small guard band, minimising loss of...

Custom filters

Filtronic has extensive knowledge and expertise in the design, development and production of custom filters that dates back to 1977. Our custom filters products include metal cavity filters, ceramic, combline, interdigital, lumped element, suspended substrate, waveguide and thin-film filters. We are experts in filter topology, offering rapid prototyping and...

Transceivers

We supply device-agnostic Microwave and mmWave transceivers, offering high-performance, competitively priced modules that significantly reduce client time to market. Our ultra-high-capacity E-band (71-76 and 81-86 GHz) mmWave transceivers are designed to deliver cost-effective, carrier-class multi-gigabit connectivity for mobile backhaul networks.  Operating in the lightly licensed 71-76 and 81-86 GHz...
