Noise Cancellation ICs: GPS

The QHx noise canceller ICs can be utilized in GPS applications to cancel local aggressors and recover the GPS receiver sensitivity. These devices are designed in a standard 0.18μm CMOS process requiring a single 1.8 V power supply. Parts are available in a standard package of
QFN16-3x3 mm² or may be ordered as bumped or bare die in a - 1x1 mm² package.

APPLICATIONS

• Standalone GPS devices
• Automotive applications
• Portable consumer devices (cell phones, game systems, laptop PCs, PDAs)
• Industrial use GPS systems
• GPS plug-in modules

FEATURES

• Actively cancels unwanted RF noise
• Improves BER, receiver sensitivity, C/N by cancelling noise generated from local aggressors
• Enables simultaneous operation of multiple co-located radios
• Can be used to cancel in-band or out-of-band interferers
  (i.e. spurs, harmonics, phase noise, or other noise sources)
• Improves overall quality of service
