8 Way Power Dividers／ Combiners
RF power divider/combiner
RF power divider/combiner is a device widely used in wireless communication systems. Its main function is to divide an input signal into multiple output signals while retaining the original signal characteristics, or to synthesize multiple input signals into one output. For a type of passive power divider, the design principle of an 8-way power divider/combiner is to construct a branch network using microstrip branch lines, and use quarter wavelength microstrip transmission lines for impedance matching, so that the impedance of each port is equal to 50 ohms. While branching, the highest efficiency of energy transmission is achieved.
The features of divider/combiner:
1. When using an 8-way power divider/combiner as a power divider, there are 1 input port and 8 output ports; When used as a combiner, there are 8 input ports and 1 output port.
2. Having electrical characteristics such as wide operating frequency, low insertion loss, high gain and isolation.
3. Mature technology and stable performance. In order to reduce the transmission efficiency caused by signal reflection, we conducted impedance matching design and optimized the port standing wave ratio; To reduce signal reflection caused by transition effects, transition from coaxial connectors to microstrip lines; To expand bandwidth and maintain low standing wave ratio, improve impedance matching branch design; To avoid resonance within the operating frequency range, optimize the cavity structure.
The applications of divider/combiner:
8-way power splitters/combiners have many applications in the RF field, providing signals for testing, synthesizing feed to and from antennas, dividing signals already transmitted and received on telephone lines, and various other purposes.
The Qualwave inc. provide 8-way power splitters/combiners with a frequency range of DC~66GHz, a power of up to 250W, a maximum insertion loss of 20dB, and a minimum isolation of 6dB. We offer various connector options such as SMA, N, TNC, N&SMA, 2.4mm, 2.92mm, etc. Our products have been widely used and praised in multiple fields.
