Description The Teledyne TDSW020A2T is a wide band, absorptive, single pole, double throw (SPDT) Switch covering dc to 20 GHz. The switch features insertion loss of 3 dB(max) and greater than 40 dB Isolation up to 20 GHz. The input power for 1dB compression is 28 dBm typical. The switch operates on +5V/-5V supplies with minimal dc power consumption and is controlled using TTL- compatible voltage levels. The die is fabricated using a robust 0.15 μm InGaAs pHEMT technology. The switch will be available in both space screened die form and an alternative 5 mm x 5 mm hermetic sealed QFN package* with space level screening.
