Abstract :
This paper presents a uniplanar passive ultra-broadband microwave mixer with 33 GHz to 67 GHz RF bandwidth and 0.5 to 34.5 GHz IF bandwidth in down-converter application with 9 ±2 dB conversion loss. The presented mixer topology is a mode conversion single balanced mixer with CPW-to-slotline RF balun and combined CPW LO and IF. An external diplexer is used as a frequency selective device to separate the LO and IF signals. This mixer is equally efficient in up & down converter applications.
