Advanced RF Switch for Space Applications
Teledyne HiRel Semiconductors has announced the release of its new rad-tolerant wideband RF switch, model TDSW050A2T. This advanced device operates over a frequency range from true DC up to 50 GHz, making it exceptionally suited for various complex applications in space and defense.
Built using a 150 nm pHEMT Indium GaAs process, the switch measures 1.15 x 1.47 x 0.1 mm, allowing for easy integration into hybrid assembly products. The TDSW050A2T has been qualified to operate within an extended temperature range of –40⁰C to 85⁰C, adhering to MIL-PRF-38534 Class K equivalency standards, which ensures reliability in extreme environmental conditions. It is currently available for immediate shipment.
Leveraging advanced MMIC design techniques, the TDSW050A2T delivers remarkable RF performance. Key features include low insertion loss, high isolation, fast switching times, and high linearity across its broad operational frequency band. The switch achieves a typical input power of 23 dBm at 1 dB compression and maintains 23 dB of port isolation at 50 GHz. It operates using ±5 V power supplies and requires minimal DC power consumption, with its control managed via TTL-compatible voltage levels.
The TDSW050A2T is specifically designed to withstand the harsh conditions of space environments. With a total ionizing dose (TID) radiation tolerance rated at 100 krad (Si), this RF switch is an excellent choice for satellite systems and other high-reliability applications in the military and defense sectors.
“Today, we’re releasing our latest wideband RF switch for K-Bands and beyond,” stated Mont Taylor, Teledyne HiRel’s vice president and business development manager. He emphasized the device’s capability to support the higher operating frequencies demanded by modern high-reliability systems, asserting its role as an ideal solution for various applications in space, military, and defense.
The TDSW050A2T is now available for orders and comfortable shipping from Teledyne HiRel Semiconductors or its authorized distributors, marking a significant advancement in RF technology for high-stakes operational environments.
