Nuvation

Nuvation has extensive RF expertise and specialized design tools. We have developed RF systems ranging from 88MHz to 24GHz frequencies. RF systems have been implemented in consumer portables, telematics (automotive), robotics, wireless base stations, radar & microwave applications, scientific test equipment, ultrasound and MRI medical imaging systems.

• Areas of Expertise:
  • FM Subcarrier
  • Bluetooth
  • 900 MHz
  • ZigBee 802.11 a/b/g/”pre-n”
  • Wireless Base Stations (CDMA, GSM)
  • High-speed “digital” circuits from 1GHz to 10GHz
  • Doppler Radar
  • GPS
  • Microwave (terrestrial and space)
