The amplifier features a specific combination of RF connectors. The input utilizes an SMA-KFD port (SMA female with a keying feature for secure connections), while the output uses a standard N-F (N-Type Female) connector, which is ideal for high-power handling up to 50W. The stringent VSWR specification of ≤1.5 ensures that signal reflection is minimized, protecting upstream components and maximizing power transfer efficiency.
