Wilkinson divider/combiner reduces insertion loss
The Vishay WLKN-000 two-way Wilkinson power divider/combiner operates from 15 GHz to 20 GHz, centered at 18 GHz. By integrating a resistor with the transmission lines, the compact surface-mount device simplifies system design and saves space in aerospace, defense, and 5G/6G connectivity applications.
Low insertion loss of <0.5 dB below 19 GHz—said to be one of the industry’s lowest—and return loss of 10 dB to 15 dB enhance system efficiency by reducing power dissipation throughout the signal path. Unlike narrowband or resistive splitters, the WLKN-000 offers high output-to-output isolation of <20 dB at the center frequency. This limits crosstalk, protects downstream amplifiers during combining, and maintains stable performance across parallel RF paths.
The thin-film device operates over a temperature range of −55°C to +155°C, supporting reliable performance in challenging environments. Applications include automotive ADAS, radio transceivers, LEO satellites, base station terminals, drones, weapons guidance systems, and phased-array radar systems.
Samples of the WLKN-000 in 1817 SMD packages are available now; production quantities have a lead time of 20 weeks.
