Vishay Intertechnology’s WLKN-000 Wilkinson power divider/combiner promises to increase efficiency and save space in aerospace, defense, and high frequency connectivity applications. Operating over a frequency range from 15 GHz to 20 GHz, the component achieves an insertion loss of less than 0.5 dB below 19 GHz in a compact surface-mount 1817 package. Specifying a return loss of 10 dB to 15 dB, the 1817 package features a three-port design that supports both divider and combiner functionality.
In contrast to narrowband or resistor-based devices, the WLKN-000 exhibits a high output-to-output isolation of less than 20 dB at the center frequency. This reportedly minimizes crosstalk, protects downstream amplifiers during combining, and preserves stable performance across parallel RF paths.
Other features include an operating temperature range from -55°C to +155°C. Applications include:
- Automotive ADAS and radio transceivers
- Low Earth orbit (LEO) satellites and base station terminals
- 5G/6G connectivity
- Drones
- Weapons guidance systems
- Payload systems
- Data-link arrays
- Phased-array radar systems
Built on thin film technology, the WLKN-000 is customizable to user specifications for frequency band, return loss, insertion loss, and case size. HFSS-encrypted models are also available.
Samples and production quantities are available now, with lead times of 20 weeks. Pricing for US delivery starts at $7.98 each/300. For greater details, procure and peruse the WLKN-000 datasheet.
