This paper presents a wire grid polarizer (WGP) working at the frequency ranges between 1 GHz to 500 GHz. The WGP is extensively used in polarization sensitive elements for separating different polarized signals at the same channel. The spacing pitch-to-width ratio should be chosen seriously for lower cross polarization levels in double polarizers. The influences between single and double layers WGP...
This work presents the thermal analysis of a Schottky diode frequency doubler capable of providing over 30 mW at 160 GHz at room temperature. This analysis includes thermal modeling of its structure and characterization at different temperature conditions. The modeling of different Schottky diode multiplier chip layouts indicates that the analyzed circuit uses the optimum configuration from the thermal...
This paper presents the design and performance of a x2x2 frequency multiplier chain from 40 to 160 GHz. The input power at 40 GHz is 500 mW with a final output power of 35 mW at 158 GHz. The 3 dB bandwidth at the output frequency is over 10%. The results demonstrate good agreement between the modeled and measured data. The work described in this paper involved extensive thermal modelling of the structure...
