Abstract
The design and operation of a multioctave double-balanced MESFET mixer operating over a 2-8-GHz range is described. Typical third-order input intercept (IP3) of +30 dBm was achieved by operating in the unbiased or passive mode with +23 dBm local oscillator (LO) input power. A quality factor is defined to show the efficiency of third-order intercept to available LO power. A single balanced MESFET mixer from 4-18-GHz with IP3 greater than +25 dBm is also discussed.<>
