Quellan’s GPS Receiver Noise Canceller

Quellan’s GPS Receiver Noise Canceller

Quellan Inc., of Santa Clara, California, offers the QHx220 active RF noise canceller for GPS applications.

Like noise cancelling headphones, the QHx220 senses unwanted internal noise and applies an opposite signal to the receive path, using sophisticated high-speed analog techniques integrated on a single one square millimeter, low-power integrated circuit.

According to the company, the canceller provides up to 25dB of cancellation, 360º of phase coverage, and operates on a single 1.8V supply voltage.
