Product Overview

The EBH220BMTV-EVALZ is an evaluation kit for testing QHx220 noise cancellation ability for a mobile TV product application. The QHx220 is a active isolation enhancer and interference canceller which is situated in a handset to sample the source of the noise and emulate the RF coupling channel between the noise source and victim receiver antenna. In doing so, an anti noise signal can be applied directly to the victim receive path to cancel the EMI and achieve the signal integrity benefits. This approach makes it possible to cancel both in band (within the victim Rx band) or out of band aggressors. The QHx220 may be used to increase the inherent isolation between antennas or inside duplexers and switches, thus allowing to increase the transmit power in repeaters or yielding higher sensitivity in the receivers. The QHx220 integrates the sampler path LNA gain stages as well as the DACs required to control the I and Q control voltages.
  • Protocol agnostic, designed for GSM, CDMA, DVB-H, ISDB-T, DMB
  • Frequency range 300MHz to 3GHz
  • Integrated, programmable LNA gain stages in the sampler path
  • SPI bus controlled integrated DACs
  • Less than 20dB noise cancellation is possible
  • 50dB typical dynamic range
  • Low power consumption
  • Actively cancels unwanted local RF noise
  • Improves overall quality of service
  • Improves isolation between adjacent antennas
