Teledyne e2v HiRel provides the Space RF engineers with off-the-shelf high frequency RF switch
A new rad-tolerant 30 GHz, Single Pole Double Throw (SPDT) reflective RF switch, model TDSW030A2T, is available from Teledyne e2v that is ideal for use in demanding high reliability, space and defence applications and comes off-the-shelf with qualified material. 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 equivalency for space applications.
The TDSW030A2T makes use of monolithic microwave integrated circuit (MMIC) design techniques that deliver superior performance in the Ku and Ka 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 30 GHz and attains an input power 1 dB compression of 25 dBm (typical). Class K equivalent element evaluation is performed per wafer.
According to Mont Taylor, Vice President and Business Development Manager at Teledyne e2v HiRel, while switching is one of the core microwave building blocks, there has been a lack of choice for designers working on high-reliability applications.
“Joining our successful release of a 20 GHz switch last autumn, this new product is the first 30 GHz switch qualified as TID radiation tolerant to 100 krad (Si) on the market,” he says.
