Milpitas, CA – December 14th, 2021 – Teledyne e2v HiRel announces the availability of a rad-tolerant 20 GHz, Single Pole Double Throw (SPDT) absorptive RF switch, model TDSW020A2T, that is ideal for use in demanding high reliability, space and defense applications and is now available with qualified material off-the-shelf. This new RF switch, developed on 0.15 μm InGaAs pHEMT technology, will be available as die and is qualified per MIL-PRF-38534 Class K-equivalent for space applications.

The TDSW020A2T leverages monolithic microwave integrated circuit (MMIC) design techniques that deliver superior performance in the Ku and K microwave and millimeter-wave bands. The switch delivers low insertion loss, high isolation, fast switching times, and high linearity across a wide frequency band from dc to 20 GHz and attains an input power 1 dB compression of 28 dBm (typical). Class K equivalent element evaluation is performed per wafer.

"We continue to expand our portfolio of high reliability RF products for Ku and K bands and beyond," said Mont Taylor, Vice President and Business Development Manager at Teledyne e2v HiRel. "This new product is the first 20 GHz switch qualified to 100 krad, and joins our growing product lines of amplifiers, low noise amplifiers, power amplifiers, DVGAs, digital step attenuators, limiters, mixers, prescalers, phase-locked loops, and switches."

The TDSW020A2T is TID radiation tolerant to 100 krad (Si), making it an excellent choice for satellites and other high altitude, high reliability applications.
