A 5-GHz radio front-end with automatically Q-tuned notch filter and VCO.

A low-voltage receiver front-end for 5-GHz radio applications is presented. The receiver consists of a low-noise amplifier (LNA) with notch filter, a voltage-controlled oscillator (VCO), and a mixer. The LNA/notch filter has an automatic Q-tuning circuit integrated with it to provide good image reje...
