The ADH986S is a wideband GaAs pHEMT MMIC Single Pole Double Throw (SPDT) switch die. This tiny switch employs a reflective topology and is controlled with two complementary inputs of 0/-3V to 0/-5V. With an input signal at 40 GHz, the ADH986S exhibits 20 dB return loss, 31 dB isolation, and only 1.9 dB insertion loss. RF performance is independent of high-level control voltages and is shown at both -3V and -5V for completeness.
