RF Circuit Design

smith iconFrom Low Frequency to Microwave, we provide custom wireless / RF circuit design solutions tailored to your specific requirements and needs, or modifications to existing designs. We have experience with a wide variety of transmitter, receiver, and transceiver solutions in a range of frequencies and standards, including broadcast, ISM, WLAN, cellular, avionics, and medical.

We can tackle a project from many different starting points: concept, prototype, or production reworks. When starting from a concept, we will first develop a system-level block diagram, and drill down into the RF circuit design. If needed, we can also design any antennas required. PCB design for prototypes is also an in-house service, allowing us to supervise the layout for good RF performance. At this phase, we can build a number of prototypes and test the system performance. After first revisions, we can test for FCC/EMI specification conformance.

System Level Design

  • System architectures, modeling, simulation
  • Link budgets, intermodulation and noise figure analysis
  • Spread spectrum/frequency hopping communication systems
  • Digital/Analog communications systems
  • RFID

RF Circuit Design

  • receivers- superheterodyne, direct conversion, super-regenerative (RKE)
  • transmitters- high and low power (up to 1 KW)
  • oscillators- VCOs, XOs, VCTCXOs
  • phase-locked loops and synthesizers, DDS
  • modulators and demodulators
  • filters –active, passive, and electronically tunable
  • couplers, matching networks, and transmission lines (microstrip, stripline, coaxial)
  • audio, digital, and power supply circuits
  • radar, RF ranging, and pulse

Antenna Design

  • LPDA, Yagi, monopoles, PIFA, and others

PCB Layout

We specialize in PCB layout for EMC and RF, using Mentor PADS. We can import and export most formats, new designs or modifications of an existing version.
