Abstract
A sub-harmonic mixer comprises two field effect transistors (FETs) in which the drains are coupled together. The mixer includes a signal generator for generating two local oscillator signals in antiphase with each other and which is arranged to feed one local oscillator signal to the source of one of the FETs and the other local oscillator signal to the source of the other FET. An input and output port is coupled to the drains for receiving input signals for the mixer and outputting output signals from the mixer.
Claims15
A sub-harmonic mixer, comprising:
- first and second field effect transistors, each having a gate, a source and a drain, the drains being coupled together,
- signal generating means for generating first and second local oscillator signals substantially in anti-phase with each other, said signal generating means being arranged to feed said first local oscillator signal to the source of said first field effect transistor and the second local oscillator signal to the source of said second field effect transistor,
- an input means coupled to said drains for receiving an input signal for the mixer, and
- an output means coupled to said drains for outputting an output signal from the mixer.
