摘要: The integrated X-band mixer described herein has been developed for an phased array system requiring a 1 GHz intermediate frequency. This high IF allows several novel design approaches. A single ended is feasible since LO noise suppression not necessary at such IF. Also, image (2f/sub LO/ - f/sub s/ ) and sum frequency (f/sub + s/) enhancement techniques can be used to recover portion, of the energy normally lost in mixing process; resulting conversion loss improvement up 1.5 dB enhanced mode as compared broadband operation. To predict "enhanced" performance, include port also account finite diode filter losses.
