RF/Microwave Design

We have extensive expertise in designing complex RF systems and components from low frequencies up to and including mm-wave bands for Bluetooth (including BLE/Smart), Wi-Fi, ZigBee, DVB-T/H, GSM, GPS, and custom proprietary standards.


Receivers, Transmitters, Transceivers

  • Custom direct conversion (zero-IF) and super-heterodyne with high speed ADC/DACs
  • 2.4 GHz Bluetooth, 2.4GHz/5.8GHz 802.11 based products
  • RF energy harvesting (RFID, battery-less sensors, wireless charging)
  • Emissions (EMI) optimization, spurious planning and avoidance (EM simulation, on-board algorithms)
  • Sideband and LO feed-through compensation
  • TX/RX feedback minimization


  • Antennas and phased arrays
  • Filters (Distributed, Lumped, Ceramic-based), Diplexers
  • Couplers
  • Matching networks (for: PA, LNA, Antenna, Mixers)
  • Combiners/splitters 


Frequency Synthesizers and Generators (up to 60GHz)

  • Sub-Hz step-size (DDS-based and Fractional PLL)
  • Ultra-low phase noise  (< 1 degree RMS jitter)
  • Fast frequency switching (using DDS, high speed DACs, switched VCOs)
  • Ultra-wideband (50MHz - 14GHz with integrated dividers, DDS based)
  • Microphonics compensation (using active feedback, passive)
