High Power Amplifiers

The U.S. Food and Drug Administration’s Center for Devices and Radiological Health is conducting market research to identify qualified small businesses capable of supplying high-power RF amplifiers designed for therapeutic ultrasound research, specifically targeting applications in histotripsy. The equipment must meet stringent technical specifications including a frequency range of 10 kHz to at least 35 MHz, output power of at least 400 watts below 10 MHz and 300 watts between 10 and 35 MHz, a minimum gain of 55 dB, 50-ohm impedance, and compatibility with standard signal generators. The amplifiers must operate on 100–264 VAC with forced air cooling and function reliably within a temperature range of 0 to 40°C. The vendor is expected to deliver two units along with comprehensive technical documentation such as calibration records, test reports, and datasheets, and must provide on-site installation and training at the FDA White Oak Campus in Silver Spring, Maryland. A three-year manufacturer’s warranty is mandatory, with an option to extend for an additional year. Respondents must submit a single capability statement no longer than ten pages in PDF or Word format, confirming their small business status under NAICS code 334220, active SAM.gov registration with a valid Unique Entity Identifier, and past performance on similar projects. The response deadline is June 2, 2026, at 12:00 PM Eastern Time, and submissions must be emailed directly to the designated point of contact; no submissions through SAM.gov are accepted. Delivery and performance must be completed within 90 days of contract award, though no formal contract has been issued. This is a sources sought notice, not a solicitation, and no contract value, award basis, evaluation factors, or binding clauses are defined at this stage. Packaging, marking, inspection criteria, payment details, and invoicing procedures are not specified in the available documentation and may be addressed in a subsequent formal solicitation.
