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.
