MM-Wave Radiometer Front-end Development

Completed TRL 4 (started at 2, targeting 4)

Description

The goal of this project is to develop integrated miniaturized millimeter-wave (MMW) reciever modules for radiometric applications. For this project we will develop an on-chip waveguide-coupled noise source, an on-chip waveguide-coupled coupler, a waveguide-packaged low-noise amplifier (LNA), and a mixer. These are enabling technologies for Earth Venture class passive MMW remote sensing applications such as atmospheric sounding, precipitation and ice cloud measurements.

Currently, we developed a MMW LNA and noise source. We designed and fabricated waveguide housing and transition circuitry, developed new processes for packaging, and packaged and characterized these two components. Both the LNA and noise source are vital components in a radiometer front-end that are not commercially available at these frequencies. The LNA will significantly reduce the noise temperature of a heterodyne receiver, enabling hyperspectral capabilities, and the noise source will allow fast internal calibration reducing mass, cost, and complexity. We will design packaging and circuitry to integrate the LNA and the noise source with other components of the receiver to develop a fully integrated miniaturized MMW receiver.

How to get involved

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
