Intellitron SDS-4000S SDR RF Sensing T/R Switch

Elevate your shack’s capabilities with the Intellitron SDS-4000S, the professional-grade RF-sensing T/R switch designed to seamlessly integrate an SDR receiver into your existing transceiver setup. By utilizing a built-in matched splitter, the SDS-4000S allows you to maintain traditional transmission while gaining the powerful spectrum and waterfall displays of a modern SDR. Whether you are chasing weak signals in a contest or monitoring a wide frequency range, this switch provides the visual and technical edge needed for superior band awareness.

Precision-engineered for reliability, the SDS-4000S features high-performance strip-line PCB architecture that ensures low SWR and minimal insertion loss up to 450 MHz. Security is paramount; the device employs an instantaneous RF-sensing circuit and a specialized protection circuit to ground the SDR input during transmission, shielding your sensitive receiver from high-power RF damage. With versatile connectivity options—including a dedicated SMA port for SDR dongles and a PTT control line for faster integration with power amplifiers—the SDS-4000S is the essential foundation for a modern, hybrid station. Don’t hunt blindly with a dial; see the entire band and protect your gear with the industrial-strength switching of Intellitron.
