directional couplers-凯发k8国际手机网页

directional couplers are one kind of rf four-port device and general standard device in microwave measurement, as well as crucial device of reflectometer and rf network analyzer, they are used to supervise
and control transmitter's output power and output spectrum, test reflected power from transmitter to antenna,monitor the matched condition of antenna feeder system. they are also taken as a power meter together with detector or level indicator.
directional couplers' features include: compact small size, light, low loss of mainline transmission,excellent flatness in frequency response of coupling value, high power capacity, stable performance and high reliability etc

3db hybrids can get the continuous sampling from transmission power along with the certain direction of transmission line and split the input signal into two equal signals with 90° difference in phase. they are mainly used to combine different signals to enhance the signal utility.
