Couplers are used to distribute or combine signals in proportion (such as 10dB coupling), while waveguide combiners directly integrate multiple signals and are suitable for high-power scenarios. Both operate in a specific frequency band, such as 2-40GHz, but have different structures and functions. Coupler Basics During ChinaSat 9B’s orbital tests, engineers found EIRP suddenly dropped […]

Waveguide combiners efficiently merge multiple signals, enhancing output power for applications like radar and telecommunications. For example, combining four 20-watt signals can yield a total output of 80 watts, improving detection range in radar systems by 20%. They minimize crosstalk to below -50 dB, ensuring signal integrity and clarity across various high-frequency applications. Signal Combination
