Receiver protectors and limiters from Teledyne Microwave UK, L to Ka band, 1 to 40 GHz, in coaxial, waveguide, microstrip and integrated module formats.
Receiver Protectors and Limiters
Engineered to absorb high-power threats from L through Ka band, 1 to 40 GHz, TMUK receiver protectors hold front-end sensitivity intact.
Receiver Protectors and LimitersReceiver protectors and limiters limit incoming RF power at the front end of EW, radar and ESM/ELINT receivers, preserving sensitivity while neutralising high-power threats. Teledyne Microwave UK builds this capability across L to Ka band, 1 to 40 GHz, in coaxial, waveguide, microstrip and integrated module formats at its Shipley and Lincoln sites.

Receiver Protectors and Limiters, Capability Overview
Receiver protection sits between the antenna and the first sensitive stage of an RF receiver. Engineered well, it combines RF limiting, filtering and switching to keep the front end intact when high-power emitters fire on or near the operating band. In EW, ESM, ELINT, radar and missile systems, the margin between sensitivity and survivability is what determines mission utility.
Engineered Capability, Not a Discrete Part
- Front-end devices such as low-noise amplifiers and mixers can be damaged by relatively short pulses well above their rated input.
- Even non-destructive overload events cause desensitisation and recovery delays that translate directly into missed intercepts.
- Modern platforms operate alongside their own emitters and within congested electromagnetic environments, raising the baseline threat level.
Construction Formats Across the Capability
- Coaxial limiters and modules for in-line use with SMA-class interfaces, simplifying drop-in upgrades.
- Waveguide variants engineered for higher microwave bands and high-power radar front ends where coax becomes impractical.
- Microstrip protection for board-level integration in compact, weight-sensitive receiver assemblies.
- Integrated modules that bring together limiting, switching and filtering into a single qualified assembly.
Why Teledyne Microwave UK
Receiver protection from TMUK is engineered, designed and built in-house at Shipley and Lincoln by the same team responsible for full receivers, oscillators, ESM/ELINT subsystems, the Phobos Radar-ESM system and Multi-Functional RF Modules. More than 50 years of RF heritage, 150+ skilled professionals and 40,000 ft² of manufacturing facilities including two dedicated clean rooms support a coherent capability rather than a sourced component.
