Teledyne e2v HiRel releases catalog radiation-tolerant 20GHz SPDT absorptive RF switch

Teledyne e2v HiRel Electronics of Milpitas, CA, USA (part of the Teledyne Defense Electronics Group that provides solutions, sub-systems and components to the space, transportation, defense and industrial markets) has made available the TDSW020A2T radiation-tolerant 20GHz single-pole double-throw (SPDT) absorptive RF switch, suitable for demanding high-reliability space and defense applications, and now available with qualified material off-the-shelf. The new RF switch, developed on 0.15μm indium gallium arsenide (InGaAs) pseudomorphic high-electron-mobility transistor (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 20GHz and attains an input power 1dB compression of 28dBm (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,” says Mont Taylor, VP & business development manager at Teledyne e2v HiRel. “This new product is the first 20GHz switch qualified to 100krad, and joins our growing product lines of amplifiers, low-noise amplifiers, power amplifiers, DVGAs, digital step attenuators, limiters, mixers, pre-scalers, phase-locked loops, and switches.”

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

Devices are available for ordering and shipment today, from Teledyne e2v HiRel or an authorized distributor, with the option of Classes H- or K-equivalent screening. They are shipped from the firm’s DoD Trusted Facility in Milpitas, CA, USA.
