RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

Saelig Introduces Versatile Dual Channel 13.6 GHz Microwave Signal Generator

Saelig Company 28 Years - RF Cafe

Innovative, low-cost, stable RF signal generator is software-tunable from 54MHz to 13.6GHz in 0.1 Hz steps

Saelig Introduces Versatile Dual Channel 13.6 GHz Microwave Signal Generator - RF Cafe10/6/2016 - Fairport, NY - Saelig Company Inc. announces the SynthHD PRO - a temperature-compensated, dual-channel, software-tunable RF signal generator and frequency sweeper, controlled and powered via a USB port on a device running Windows or Android software. The Windfreak Technologies SynthHD PRO's dual, independent 54 MHz to 13.6 GHz channels can be configured to run at two different frequencies, or at the same frequency with different phases. This allows its use in antenna beam steering applications or quadrature signal generation commonly used in image-reject frequency conversion. The SynthHD PRO also has nonvolatile on board memory so it can be programmed to start up by itself on any frequency, power, sweep or modulation setting (or combinations thereof) to run stand-alone in field use. This makes it a highly mobile, low power, and light weight signal source for many RF signal generation needs.

HD stands for High Definition:

  • 54 MHZ to 13.6 GHZ in 0.1 Hz steps
  • -50 dBm to +20 dBm (typical) in 0.01 dB steps
  • Set each channel to independent frequencies and amplitudes
  • 0 to 360 degrees coherent phase control in 0.01 degree steps on each channel
  • Stack multiple devices for coherent phase control on every channel
  • Select internal 10 or 27MHz reference or use external 10-100MHz reference
  • Pulse, AM and FM internal modulation including FMCW radar chirp
  • Pulse Modulation with 1uS minimum width and 1uS resolution
  • Pulse, AM and FM external modulation from DC – 10KHz
  • Powerful Trigger modes allow external triggering of most functions without a PC connected
  • Linear and list mode (frequency and amplitude hopping) sweeps include dual channel differential sweeps
  • Save all settings to the device for use without a PC
  • 32 bit ARM processor on board which is Arduino compatible (Teensy 3.2)
  • Digital schematics and complete Labview GUI executable and source code (pictured below) included with purchase
  • Top and bottom side PCB snap connector locations brings 20 power, analog and digital I/Os to your custom mezzanine boards
  • Windows, Linux and Android compatibility
  • Designed and manufactured in the USA with maximized value / cost ratio

The Windfreak Technologies SynthHD PRO's typical channel output power is 20dBm maximum and -40dBm minimum, with the variable gain set via a 16-bit D/A. Each RF channel's power and frequency is independent, with dBm power levels settable in 0.01dB increments and frequency resolution of 0.1Hz or less with 2.5ppm frequency accuracy. For more complex applications the SynthHD PRO also has an internal 100 point Frequency and Amplitude Hop Table, with a 0.01 degree phase control on each channel and a fast 4mS RF lock time.

On-board calibration is attained through a user-programmable look up table, plus two overall bias constants. Full unique device calibration can be performed at the factory and stored in onboard EEPROM. All parts of the signal chain have high quality voltage regulation, and the D/A's driving the VGAs have a 1% voltage reference controlling their outputs. The SynthHD PRO can measure its own temperature, allowing for excellent power and frequency control over a wide temperature range. Open source Labview GUI software, which features an Absolute Power display, is provided for setup and control of the unit via a USB port. 

Compact in size (2.8" X 2.2"), the Windfreak Technologies SynthHD PRO will find application in wireless communications systems design, antenna beam steering, quadrature oscillators for image-reject mixers, RF and microwave radios, software-defined radio (SDR), radar systems including FMCW, automated test equipment (ATE), radiated immunity pre-compliance EMC testing, etc.

Designed and manufactured in USA by Windfreak Technologies, a designer of low cost, innovative RF products that are in use worldwide in a variety of technical applications, the SynthHD PRO is a highly mobile, low power, lightweight solution for sophisticated RF signal generation needs. It is available now from Saelig Company, Inc. Fairport, NY.
