2026-04-13

This device adopts a compact 1817 SMD package, with a working frequency range of 15 GHz to 20 GHz, and an insertion loss of less than 0.5 dB below 19 GHz

Recently, Vishay Intertechnology, Inc. (NYSE stock code: VSH) announced the launch of a new dual Wilkinson power divider/synthesizer, WLKN-000, aimed at improving efficiency and saving space in aerospace and high-frequency connectivity applications. The Vishay Sfernice WLKN-000 has a wide operating frequency range, covering 15 GHz to 20 GHz. It adopts an integrated surface mount package and can achieve industry-leading insertion loss of less than 0.5 dB in the frequency range below 19 GHz.

The recently released device supports a wide frequency range with a return loss of 10 dB to 15 dB. This not only simplifies the system design, but also reduces the required external components, thereby saving circuit board space and lowering costs. Its compact 1817 package integrates a three port solution that supports both splitter and combiner functions, simplifying the layout. The low insertion loss of this device can minimize power consumption in the signal path, thereby improving system efficiency.

Unlike narrowband or resistance based solutions, WLKN-000 provides high output to output isolation, with less than 20 dB at center frequency, minimizing crosstalk, protecting downstream amplifiers during signal merging, and ensuring stable performance on parallel RF paths. In addition, the device provides excellent matching characteristics throughout the entire operating frequency band.

-The wide temperature range of 55 ° C to+155 ° C ensures reliable performance of the product in various demanding applications. These applications include advanced driver assistance systems (ADAS) and wireless transceivers for automobiles; Low Earth Orbit (LEO) satellites and base station terminals; 5G/6G connection; UAV; Payload system; Data link array; And phased array radar system.

WLKN-000 is manufactured using thin-film technology, compliant with RoHS standards, halogen-free, and meets Vishay green standards. This device can be customized according to customer specifications such as frequency band, return loss, insertion loss, and housing size. The HFSS encryption model can also be provided.

WLKN-000 can now provide samples and has achieved mass production, with a supply cycle of 20 weeks.
