The small yet powerful Sparrow is the optimal front-end tuner for both commercial and military systems that search, intercept and locate electromagnetic energy.  Key threat detection applications include COMINT, ELINT, ESM and EW operations. Configurable as a single or dual channel tuner, each channel covers the VHF, UHF and SHF spectrums with an input frequency range of 70 MHz to 18.25 GHz and a 500 MHz ultra-wide bandwidth.  Sparrow’s ability to see weak signals in the presence of strong interferers and superior signal fidelity all within a compact 3U VPX form factor, allows users to confidently deploy Sparrow in the most demanding signal environments and achieve performance that far exceeds larger products.

The Sparrow is backed by a standard three year warranty (some restrictions may apply). We are committed to providing outstanding product reliability and support so you can focus on mission success.

Applications Supported

Military Applications for Sparrow RF TunerMilitary Applications

Sparrow is the optimal front-end tuner for military systems performing critical operations. COMINT, ELINT, EW and ESM applications are performed through independent or phase-coherent tuning across multiple 3U VPX units to search and locate sources of electromagnetic energy in order to detect and warn of threats.

Applications for Sparrow RF TunerOther Applications

Spectrum monitoring, testing and measuring radio frequencies and wideband spectral sensing, are a few of the applications supported by Sparrow that benefit both the defense and commercial industries.
