In this work the design and integration of 60 GHz monolithic microwave integrated circuit (MMIC) transceiver using 0.15 um Gallium Nitride (GaN) Qorvo process that will support the Wireless Gigabit Alliance (WiGig)/802.11ad radio specifications will be presented. The wideband GaN Power Amplifier (PA) can operate at 60–65 GHz with output power of 27 dBm and large signal gain of 23.5 dB. The wideband...
The Fabry-Perot open resonator is widely recognized for the measurement of dielectric permittivity and loss tangent for low-loss materials at high frequencies. A 10 nanometer step of the cavity length variation increases the quality factor to 100,000 or more, thus allowing the loss tangent measurement with high precision. Such a small step size often introduces mismatch of the computer clock rate...
In this paper, a special designed transverse slotted cavity is built in X-band to Ka-band. It was applied to determine the complex permittivity of a novel “ceramic state” polymer electrolytes by employing perturbation theory. The dielectric spectra of this material had been characterized. The complex alternating current electrical conductivity and the ionic conductivity can be deserved from the complex...
A precision automated open resonator system is designed and constructed for the measurement of loss tangent and dielectric permittivity of low absorbing materials at 60 GHz. The high Q hemispherical Fabry-Perot cavity together with highly stabilized synthesized phase locked Gunn oscillator sources and the super heterodyne receiver enable us to measure loss tangent value as low as 10 micro-radians.
