A coupler antenna splits or combines signals, matches impedance, filters frequencies, and measures signal power. For example, in a 1,000-watt system, it diverts 10 watts for monitoring, ensuring 95% efficiency. Costs range from $500 to $2,000. Signal Splitting Signal splitting using coupler antennas is a fundamental technology in modern communication systems, enabling multiple devices to […]

To test a directional coupler, apply a 0 dBm signal and measure key parameters. For instance, verify coupling factor (-20 dBm for 20 dB coupling), insertion loss (-1 dBm for 1 dB loss), and directivity (30 dB if isolated port reads -50 dBm). Ensure all unused ports are 50-ohm terminated. Verify Coupler Specifications Testing the
