## Abstract In this paper, a subharmonic cascode FET mixer is proposed to improve the isolation characteristic between the local oscillator (LO) and RF ports of an unbalanced mixer. The mixer is designed by using a single‐gate FET cascode structure and driven by the second harmonic component of the

## Abstract This paper presents the voltage‐controlled oscillator (VCO) with a cascade FET structure and self‐oscillatory property. The self‐oscillation (SO) frequency of the designed VCO is 1.45 GHz and the frequency is tuned from 1.06 to 1.42 GHz by using an added varactor diode. Mixing SO signal
## Abstract A direct‐conversion mixer with zero‐bias current for IMT‐2000 application is designed by using the resistive cascode FET structure and is driven by the 2^nd^‐harmonic of the local oscillator (LO) signal. Due to the zero‐bias current operation of the cascode FET, the designed mixer has c
