Q-Tech launches Lamb Wave Oscillators for low-noise high-frequency RF designs

Q-Tech Corporation launched its QT25HF and QT25VHF Lamb Wave Oscillator family on June 10, 2026, targeting RF systems from 400 MHz to 1.3 GHz. The company says the parts combine SAW-like noise performance with crystal-oscillator-level frequency stability for aerospace, defense and industrial uses.

Why it matters: - Q-Tech is targeting engineers who need a high-frequency reference that holds tight specs across wide temperature swings. - The QT25 family is aimed at aerospace, defense and industrial systems where phase noise, jitter, size and thermal robustness directly affect performance and qualification risk. - Q-Tech says the new oscillators deliver an order-of-magnitude improvement in frequency stability versus typical SAW resonators.

What happened: - Q Tech Corporation announced the QT25HF Lamb Wave Oscillator and QT25VHF Voltage Controlled Lamb Wave Oscillator on June 10, 2026. - The new products are designed for radio-frequency applications from 400 MHz to 1.3 GHz. - Q-Tech says the oscillators are built as a compact drop-in package for severe-environment applications.

The details: - The QT25HF offers ±50 ppm stability over -55°C to +125°C. - The QT25HF can be as tight as ±20 ppm over -20°C to +70°C. - The company says the family delivers ultra-low phase noise with a floor of -168 dBc/Hz. - Q-Tech says the published phase-noise data corresponds to 8.08 femtoseconds of calculated integrated RMS jitter at 500 MHz. - The product line is intended to provide crystal-oscillator-like temperature stability at much higher frequencies than standard crystal oscillators. - Q-Tech says the design is optimized for low phase-noise, high-frequency applications. - Q-Tech says the devices are intended to simplify integration and reduce lifecycle risk.

Between the lines: - The launch signals demand for frequency sources that bridge the gap between SAW-based parts and traditional crystal oscillators. - Q-Tech is positioning Lamb Wave Oscillators as a practical path to higher RF performance without forcing designers to trade away thermal stability. - The comparison to typical SAW stability of 250 ppm over -40°C to +85°C highlights where Q-Tech is trying to differentiate. - Fred Wolff, Q-Tech’s director of business development, said customers have been asking for GHz-class sources that mirror XO stability and are easier to qualify.

What’s next: - Designers in aerospace, defense and industrial markets will now evaluate the QT25 family for new and existing RF platforms. - Q-Tech will likely lean on the compact drop-in format and stability specs to push qualification discussions with OEMs. - The company also continues to market its broader frequency-control portfolio and global sales reach across North America, Europe and Asia.

The bottom line: - Q-Tech is betting Lamb Wave Oscillators can give RF engineers SAW-like noise performance with much tighter stability at GHz-class frequencies.
