Decade-band mixer covers 3.5 to 35 GHz
Abstract
The development of broadband components for use in receiving systems operating through 40 GHz is of interest because of possible applications in a number of electronic warfare (EW) systems. This paper is concerned with the front-end mixer, which is a key component in broadband receivers, taking into account the design and performance of completely planar broadband double-balanced microstrip mixers. Attention is given to the traditional double-balanced diode mixer, the beam-lead GaAs mixer diode model, details regarding the design of broadband mixers, a local oscillator (LO) port model with tapered balun, an RF port model (resonant balun), a complete mixer transmission line model, an 18 to 40 GHz double-balanced mixer, and the conversion performance of the 18 to 40 GHz mixer. Double-balanced broadband mixer design techniques are modified and implemented to derive a new class of mixers operational through 40 GHz.
