Abstract
A GaAs MMIC Voltage Variable Attenuator (WA) has been developed for use at millimeter wave (MMW) frequencies incorporating triple-gate 0.25 μm power MESFET devices. This circuit exhibits exceptional power handling capabilities at all attenuation states, handling a minimum of 10 dBm input power, which occurs at it’s 3 dB attenuation state, and greater than 26 dBm while operating in it’s minimum attenuation state. The triple-gate WA measures 1.7 dB in the low attenuation state and greater than 32 dB in the high attenuation state at 30 GHz. Additional on-wafer small signal and large signal measurement data is presented and compared to a similar single-gate MESFET WA.
