Radiation Tolerant 60 GHz Reflective SPDT RF Switch for NextGen Space Applications

Teledyne e2v HiRel, a leading provider of semiconductor solutions for the Defense, Space and Commercial markets has released a new rad-tolerant 60 GHz, Single Pole Double Throw (SPDT) reflective RF switch. The new model, TDSW0602T, is ideal for use in high reliability, demanding space and defense applications.

This new RF switch, developed with Silicon-on-Insulator (SOI) technology, will be available as a flip chip die and is screened per MIL-PRF-38534 Class K for space applications. Until now, rad tolerant (radiation tolerant) 60 GHz switch technology has only been available for less rigorous commercial application requirements. The product leverages monolithic microwave integrated circuit (MMIC) design techniques that deliver unprecedented performance in the K and Ka microwave and millimeter-wave bands for customers.

The TDSW0602T delivers benchmark low insertion loss, high isolation, fast switching times, and high linearity across a wide frequency band from 20 kHz to 60 GHz. The element evaluation is performed per wafer, per MIL-PRF-38534 Class K.

The RF switch is manufactured on an UltraCMOS process, an advanced form of SOI technology that delivers the performance of GaAs with the economy and integration of conventional CMOS (UltraCMOS is a registered trademark of Peregrine Semiconductor Corporation). The SOI process has space-flight heritage and is TID radiation tolerant to 20 krad and immune to SEL (Single Event Latchup), making it an excellent choice for satellites and other high-altitude, high reliability applications.
