High-frequency RF systems operating in radar, electronic warfare, and communications environments require reliable signal isolation without adding size or integration complexity. TTM Technologies addresses this need with a full portfolio of high-performance RF and microwave circulators designed to provide controlled signal routing, isolation, and reflection management across aerospace & defense and commercial applications.
TTM’s circulators use patented non-reciprocal designs to control signal flow, provide high isolation, and protect RF systems from reflected power. These devices are optimized for phased-array radar antennas, EW systems, and high-reliability communication platforms, where insertion loss, power handling, and consistency directly impact system performance.
A key differentiator is TTM’s focus on compact, surface-mount (SMT) form factors that are pick-and-place compatible, enabling seamless integration into high-density RF assemblies. X-Band SMT circulators in the portfolio support frequency ranges from approximately 8.5 to 11 GHz, offer low insertion loss (as low as ~0.5 to 0.6 dB), isolation up to 30 dB (dual-junction designs), and continuous-wave power handling up to 20 W, while operating in environments from -40 to +85°C.
These circulators are engineered to withstand typical MIL ground and airborne conditions, making them suitable for harsh operational environments. Consistent RF performance across production lots supports high-volume deployments, a critical requirement for phased-array and distributed RF architectures.
Beyond standard catalog offerings, TTM specializes in custom circulator solutions, including UHF through Ku-band designs, tailored to specific frequency, bandwidth, power, and mechanical constraints. Design, automated manufacturing, and RF testing are performed at TTM’s U.S. facilities, ensuring controlled quality and DFARS-compliant sourcing of permanent magnets for defense programs.
