High-performance and high-reliability RF for LMR, LTE and Converged Networks
Filtronic’s products are integral to advanced radio networks, ensuring dispatchers can instantly communicate critical information to first responders in the field, enhancing public safety. When reliable communication is crucial for public safety, they can depend on Filtronic’s infrastructure to deliver seamless communication the first time, every time. Filtronic designs and manufactures purpose-built solutions that provide high-performance communications for first responders when seconds count.
Our precision products for critical communication applications include tower top amplifiers, filters, crossband/in-band combiners, power amplifiers and multiplexers. We collaborate with the leading critical communication OEM’s, acting as their RF partners. Our innovations and technical skill have improved miniaturisation, reducing the footprint and weight of our components, while increasing power and amplification to improve connectivity
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.
We provide full US-based assembly, and have been instrumental in reshoring some products and process for our customers. We can offer a range of tailored solutions from our modern manufacturing plant in Salisbury, Maryland, providing our customers a world class service that adds value to their supply chain. By helping our clients to remove cost from their operations, reducing their labour costs, improving their processes by removing waste. We also reduce time to market, giving our clients the flexibility to ramp up and down rapidly, improving quality all with no additional overheads or purchasing capital equipment.

Critical communications RF filters
RF filters play a crucial role in emergency first response networks, ensuring reliable communication during critical situations. Filtronics capabilities in filters 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 reduced development cycles. Our team of highly experienced engineers work with customers to ascertain optimum technologies dependent upon specific filter requirements, e.g. size, response, power handling, insertion loss and rejection.

What we do
Critical communications RF products
Tower Top Amplifiers
Overview Our Tower Top Amplifier (TTA) systems are engineered to enhance the performance of critical communication networks, particularly in 700 and 800 MHz bands. These systems improve base station receiver sensitivity by amplifying weak signals at the tower top, thereby reducing signal loss associated with feeder cables. This enhancement is crucial for...
Cross band combiners
Cross-band combiners enable signals from multiple base stations of different bands to be combined onto a single pair of feeders which speeds up deployment, saves the cost of additional feeders and when used with ultrawideband antennas and multi-band TMAs, reduced site clutter. Cross-band combiners are used to combine multiple...
In band combiners
Due to the increasing restriction on tower infrastructure deployments by local municipal policies and the physical limitations of towers, operators are facing difficulties in adding new antenna systems to their existing sites. Network equipment sharing between multiple operators or multiple technologies are a cost-effective solution to the deployment 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...
