The SI-9249/FE12 is a single-channel frequency extender designed to expand the frequency range of receivers and tuners operating in the VHF/UHF band to 3 GHz through 12.4 GHz, enabling the detection of microwave signals.

The Frequency Extender can be controlled remotely via its multi-drop RS-232 interface, or manually via its bottom panel DIP switches. In combined operation, it can be daisy-chained to other units via a multi-drop RS-232 connection and 10 MHz reference output, eliminating complex cabling. The Frequency Extender features a built-in low-noise amplifier, that when used with VHF/UHF receivers, it can improve a receiver’s noise performance.

Extending the Frequency of VHF/UHF Receivers

If a signal of interest is detected outside of the VHF/UHF range, the signal is converted to an acceptable frequency for the device to ensure you are capturing the right signals.
