Defense & Electronic Warfare
Phased array radar · Electronic warfare · Missile guidance · Military communications - Complete RF solutions from core chips to precision interconnects
Since its founding in 1996 as a joint venture between Airbus and Thales, UMS has been at the heart of European defense innovation.
Our mission: to develop and supply sovereign, high-performance RF components for ground-based, airborne, naval, and spaceborne radar systems and electronic warfare platforms.
As an authorized distributor for UMS, TMT provides customers in the defense sector with access to these industry-leading components,
along with professional technical support for component selection, parameter matching, and system integration.
Defense RF Application Scenarios
Phased Array Radar
Modern phased array radars rely on core RF chips in thousands of T/R modules to achieve rapid beam scanning and multi-target tracking. UMS CHP series phase shifters provide precise phase control; CHA series power amplifiers drive high-power transmission; CHS series switches enable rapid transmit/receive switching - these three core chips form the RF backbone of phased array T/R modules.
Electronic Warfare (EW)
Electronic warfare systems require broadband, fast-response RF front-ends. UMS broadband GaAs/GaN amplifiers cover multiple threat frequency bands; Variable Gain Amplifiers (VGA) enable dynamic power management and precision modulation of jamming signals. Southwest Microwave high-reliability End Launch connectors ensure low-loss interconnects between EW modules.
Missile Guidance
Active radar seekers require miniaturized, high-reliability RF links. UMS integrated downconverters with LNAs provide high-sensitivity receive channels; GaN power amplifiers deliver high-power transmission in compact packages. All devices meet military operating temperature and vibration requirements.
Military Communications
Tactical communications and data links require anti-jam, low-probability-of-intercept (LPI) RF design. UMS LNAs improve receiver sensitivity; mixers and VCOs support fast frequency hopping; switches and attenuators enable power management and band selection. Southwest military-grade connectors ensure signal integrity in harsh environments.
