High Performance Miniature Bandpass Filters

This proposal is submitted for developing low impedance, miniature bandpass RF frequency filter via MEMS technique, in applications of SMAP, Aquarius follow-on, DESDynI, or Advanced L-band SAR and interferometers.

The proposed innovative, small size, low impedance, bandpass RF frequency filters are ideal candidates for next generation cell phone applications. The current bandpass filter products in cell phone applications (mostly made of FBAR techniques) are bulky and can not meet the future cell phone development requirements. The development tendency requires the next generation cell phone to be multifunctional so it can accept multiple services for multiple applications, with no larger than current dimensions. The potential market size for compact bandpass RF filters is huge, from $176 millions in the US to $2.6 billions worldwide each year.

The proposed low impedance, miniature bandpass RF frequency filters can be used in applications of SMAP, Aquarius follow-on, DESDynI, or Advanced L-band SAR and interferometers, as well as other communication, signal process in aerospace and ground application in NASA.

This is early/mid-stage (TRL 5) — 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.
