Wideband GaAs integrated-circuit (IC) switch model ISO13316 is a single-pole, single-throw (SPST) switch with low loss and high isolation from DC to 6 GHz. The hermetic switch, which is suitable for high-reliability space, satellite, and defense applications, provides 45-dB isolation at 2 GHz with low loss of 1.1 dB at 6 GHz. Isolation ranges from typically 57 dB through 2 GHz, 51 dB through 3 GHz, and 30 dB through 6 GHz, while insertion loss is typically 0.6 dB through 3 GHz and 0.78 dB through 6 GHz. The switch is produced with a GaAs pseudomorphic-high-electron-mobility-transistor (pHEMT) process that has been shown to be radiation tolerance to 100 krad. The switch, with typical 10%/90% and 90%/10% RF switching speed of 5 ns, is supplied in a seven-lead surface-mount-technology (SMT) package measuring 0.385 × 0.345 × 0.065 in.
