MM-WAVE DEVICES / TRI-BAND POWER METER — UNDER DEVELOPMENT

Millimeter-Wave Power Meter

Power measurement in the millimeter-wave and sub-terahertz bands has traditionally meant expensive, slow thermal power meters. The "Tri-Band mm-Wave Power Meter" we are developing carries three waveguide ports — WR-10, WR-6, and WR-3 — in a single unit, covering 75 GHz to 330 GHz with one instrument, with a cost-conscious design (currently at the proof-of-concept stage). Fast diode-detection measurement lowers the barrier to entry for millimeter-wave and sub-terahertz testing.

Features

Low costDesigned for lower cost than conventional thermal power meters, lowering the barrier to millimeter-wave and sub-terahertz measurement.
Fast, precise detectionZero-bias Schottky diode detection captures small powers quickly and precisely — several hundred readings/s make tuning work efficient.
Internal calibration & temperature compensationFrequency response is internally calibrated based on the selected measurement frequency; a temperature sensor provides temperature compensation.
Robust software designFirmware implemented in memory-safe Rust; the measurement core logic is verified by over 70 automated tests.

Appearance & Key Specifications (Preliminary)

POC

Three waveguide ports as standard

WR-10, WR-6, and WR-3 are fixed in one unit; band switching is simply a matter of port selection. Operate it stand-alone via the color LCD and rotary encoder, or from the PC app (real-time graphing, CSV logging, automated control). Custom waveguides and antenna-fitted variants are available on request.
