    The SynthHD PRO is 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 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 compact solution for many RF signal generation needs.

    The 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 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 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. 

    SynthHD Pro Software GUI (Labview source code included with purchase)

    The following video shows the SynthHD Pro doing a Pulsed FM Radar Chirp (FMCW) that is simultaneously AM modulated.

    The video below is taken with both channels driven into a mixer. The mixer is then fed into an oscilloscope and displayed on the right side of the video. The signal shows the DC and near DC downconverted component. The DC level depends on the phase relationship between the two channels. The switch on the far right of the GUI toggles between controlling channels (RFA or RFB).
