This paper presents the characterization measurements and simulations performed with ACST InGaAs low-barrier Schottky diodes for millimeter wave mixing applications. While these low-barrier Schottky diodes have been successfully used for millimeter wave detector design, their performance when acting as mixers has not been tested yet. This paper shows the performance for this type of diodes in a fundamental...
This paper describes the development and characterisation of broadband radiometers centered at 94 and 183 GHz for passive millimeter wave imaging and NDT applications. The W-band radiometer has been built and tested using both fundamental and sub-harmonic mixer configurations. The 183 GHz radiometer uses a sub-harmonic mixer at the front-end and has an LO that is common with the fundamentally pumped...
This paper presents the design, fabrication and measurements of a fourth-harmonic Schottky diode mixer working at sub-millimeter frequencies, in particular at an RF frequency of 440 GHz. Measured DSB noise temperature of 7900 K and conversion loss of 14 dB have been obtained. This configuration offers an alternative solution which simplifies the LO signal generation. It can find an application in...
