The SI-9138 is a wideband VHF/UHF tuner covering a 2 MHz to 6 GHz input frequency range. The unit has state-of-the-art dynamic range and phase noise performance, a maximum instantaneous bandwidth of 40 MHz and selectable analog bandwidths of 3, 10, 25 and 40 MHz. With a tuning setting time of 50 microseconds, multichannel phase-coherency and time tagging of its Digital IF output, the SI-9138 is key to the SI-8938’s deployment in spectral search, direction finding and geo-location missions.

The SI-9138 and SI-7138 work together to create the SI-8938 subsystem providing phase-coherent, wideband tuning of up to eight tuner channels across the 2 MHz to 6 GHz range. Based on proven RF technology and an open backplane standard, the SI-8938 provides a powerful and low-SWaP software-definable receiver development platform that can easily be integrated and deployed in a range of missions.
