Summary of moRFeus – A field-configurable wideband frequency converter and signal generator
MoRFeus is a compact, field-configurable Fractional-N frequency converter and signal generator operating from 30 MHz to 6 GHz. Featuring an LCD display and button interface, it allows dynamic LO setting and mode toggling between mixer and generator functions. Designed for low spurious emissions in a precision-milled aluminum enclosure, it supports USB programming and active antenna biasing for diverse RF applications like SDRs, satellite comms, and test equipment.
Parts used in the MoRFeus Project:
- Fractional-N synthesizer
- LCD display with backlight
- Button control interface
- SMA connectors
- External micro-USB 5 V power supply
- Precision-milled aluminum enclosure
- RF choke for bias voltage
- USB HID programmable interface
MoRFeus is a 30 MHz–6 GHz field-configurable Fractional-N wideband frequency converter and signal generator. Its LCD display and button interface enable dynamic field-level configuration – from switching between signal generator and other modes, to setting the local oscillator frequency and more. It was designed for wideband frequency up- and down-conversion – with an LO frequency range of 85 MHz–5.4 GHz and input/output frequency range of 30 MHz–6 GHz
MoRFeus is small, lightweight, and functional. It was designed for low spurious emissions and is packaged in a precision-milled aluminum enclosure.
Product development for moRFeus is done, so we’ll be shipping soon. And it’s only $149 if you act fast.
Use cases for moRFeus are many

How it works
MoRFeus integrates into popular RF environments using SMA connectors and is powered using an external micro-USB 5 V supply. The LCD display and button interface provide a dynamic way to program the mixer LO frequency in the field with a step size of 1.5–3 Hz*. Dynamic toggling between mixer and generator modes adds to field-level functionality. An optional bias voltage of 5 V is available via RF choke to the mixer input to supply active antenna systems. The device is also USB HID programmable, enabling automatic operation from a PC running Windows or Linux.
