hybrid combiner n-female Application:

Through hybrid combiner n-female, the large signal can be converted into a small signal with measuring characteristics, which is suitable for the input requirements of measuring instruments such as microwave power meter (RF power meter). hybrid combiner n-female reduces the amplitude of the input signal. In addition to reducing the amplitude (power) of the output signal, hybrid combiner n-female still maintains its own signal features and carried information, including frequency, waveform, and bandwidth. Still can be used to measure frequency, display waveform spectrum and demodulation, by compensating the amount of attenuation, still can measure the amplitude of the original signal (power). hybrid combiner n-female attenuates signal power energy, converts excess acting energy into heat and dissipates, which conforms to the law of energy conservation. In low-power applications, you do not need to consider the heat dissipation of the attenuator. However, in high-power applications, the heat dissipation characteristics of hybrid combiner n-female become a concern. That is why the hybrid combiner n-female is covered with heat sinks.

For example, measure an 80w microwave signal source (microwave signal generator). Since the output power is relatively large, we need to use a hybrid combiner n-female of 30dB (attenuation 1000 times), so that the 80w signal becomes 0.08w after the attenuator, which is suitable for microwave power meter (RF power meter). Signal input amplitude requirements of instruments such as frequency meter and spectrum analyzer (most high-frequency instrument sensors do not support high power direct input).

On the other hand, hybrid combiner n-female can be used to extend the range of measuring instruments such as microwave power meter (RF power meter). For example, the range of a microwave power meter (RF power meter) with the highest test power of 0.1W can be extended by 1000 times by using a 30dBhybrid combiner n-female (signal attenuation 1000 times) with sufficient power. It can be used to measure microwave signals up to 100W high. According to the previous example, an 80w power signal passes a 30dBhybrid combiner n-female, and the output power is 0.08w. Then the remaining 79.92W power needs to be converted into heat dissipation on hybrid combiner n-female. You can see the importance of hybrid combiner n-female heat dissipation. The surface of many large and medium-sized attenuators is marked with high temperature. hybrid combiner n-female The surface temperature is high enough to cause extreme temperature when the device works under high load for a long time. hybrid combiner n-female If the input power exceeds the designed power, the internal temperature is too high, causing damage.

In addition to the external hybrid combiner n-female we often see, in fact, many instruments have built-in attenuators, whose function is also to attenuate signals. For example, most signal generators use built-in adjustable and variable attenuators to control the amplitude of the signal output. Variable attenuators are also used in the input networks of microwave power meters (RF power meters), spectrometers, and general testers to extend the instrument's range.
