A novel, compact Ka-band MMIC (monolithic microwave integrated circuit) voltage controlled oscillator (VCO) has been designed, fabricated and tested. The VCO design is a 'ring' configuration using two FETs with two isolated control terminals, which p

A millimeter-wave resistive (intermediate frequency) FET mixer design that provides down-conversion to low IF (intermediate frequency) frequencies with low 1/f noise is described. The single FET unbalanced mixer has a double sideband noise figure of
