Teledyne HiRel Semiconductors has released the TDSW050A2T, a rad-tolerant wideband RF switch for high-reliability space, military, and defense applications operating from true DC to 50 GHz.
A High-Performance RF Switch for Complex, High-Frequency Systems
Developed using a 150nm pseudomorphic High Electron Mobility Transistor (pHEMT) Indium Gallium Arsenide (InGaAs) process, the RF switch is available in an ultra-compact 1.15 mm x 1.47 mm x 0.1 mm die, making it well-suited for hybrid assembly products.
Its design leverages monolithic microwave integrated circuit (MMIC) techniques to deliver superior performance across frequencies up to millimeter-wave bands. The RF switch provides low insertion loss, high isolation, fast switching times, and high linearity across a broad frequency range.
The device achieves an input power 1 dB compression point of 23 dBm (typical) and offers 23 dB of port isolation at 50 GHz, ensuring continued signal integrity and reliability in advanced RF applications. It operates with ±5V power supplies, consumes minimal DC power, and is controlled via TTL-compatible voltage levels, ensuring seamless system architecture integration. Class K equivalent element evaluation is performed per wafer.
Designed for extreme environments, the TDSW050A2T also meets stringent performance requirements across an extended operating temperature range of –40⁰C to 85⁰C. Its radiation tolerance up to 100 krad (Si) makes it well-suited for satellite communications, deep-space exploration, and other space-based systems where exposure to high radiation levels is a key design consideration.
“Today, we’re releasing our latest wideband RF switch for K bands and beyond,” said Mont Taylor, Vice President and Business Development Manager at Teledyne HiRel. “To meet the higher operating frequencies associated with many of today’s high-reliability systems, this RF switch supports operation from true DC out to 50 GHz, making it an ideal solution for space, military, and defense applications.”
Product Availability and Ordering
The TDSW050A2T is available for immediate order and shipment through Teledyne HiRel Semiconductors or authorized distributors. All units are manufactured and shipped from Teledyne HiRel’s DoD Trusted Facility in Milpitas, California.
