Recent Company History

Over the last several weeks, Vishay has repeatedly introduced new components across automotive, sensing, space-grade, LED, and industrial optocoupler markets. Product launches on Feb 25, Mar 4, Mar 18, Mar 25, and Apr 1 produced mostly small price moves, with reactions ranging from about -1% to +2.5%. Today’s RF power divider / combiner fits this pattern of incremental portfolio expansion rather than a single transformative event, and prior history suggests such news has driven only modest, mixed price responses.

Analysis

The stock moved +8.0% in the session following this news. A strong positive reaction aligns with Vishay’s pattern of frequent product introductions, though past moves around similar launches have typically been limited to a few percentage points. Investors would likely watch how this RF component contributes to broader aerospace, defense, and connectivity design wins. Key risks would include enthusiasm fading if orders or design-ins lag expectations, or if broader semiconductor sentiment turned, given the stock’s position above its 200-day MA.

6 terms

wilkinson power divider technical

"introduced a new 2-way Wilkinson power divider / combiner designed to increase efficiency"

A Wilkinson power divider is an electronic component that splits a radio-frequency signal into two or more equal parts while keeping the output paths isolated so they do not interfere with each other. For investors, it matters because it is a fundamental building block in wireless, radar, and telecom equipment—its performance affects product reliability, efficiency, and competitive positioning, much like a well-designed traffic splitter that routes cars smoothly without causing jams.

insertion loss technical

"provides industry-low insertion loss of < 0.5 dB below 19 GHz"

Insertion loss measures how much a signal (like electricity, radio waves, or light) is weakened when a component or cable is added into a transmission path; imagine adding a narrower section of pipe that reduces water flow. It matters to investors because higher insertion loss can reduce a product’s performance or efficiency, affect regulatory approval and customer acceptance, and therefore influence production costs, competitive position, and revenue potential.

crosstalk technical

"high output to output isolation — < 20 dB at the center frequency — to minimize crosstalk"

Unwanted interaction or interference between two signals, systems, or biological pathways that causes unclear, mixed, or misleading results. For investors, crosstalk can change how a product, test, or device performs in the real world — like two radio stations bleeding into each other — which can affect clinical trial outcomes, regulatory reviews, product reliability, and ultimately a company’s revenue and risk profile.

thin film technology technical

"RoHS-compliant, halogen-free, and Vishay Green, the WLKN-000 is built on thin film technology"

Thin film technology uses extremely thin layers of material—often just atoms to micrometers thick—deposited onto a surface to give that surface new electrical, optical, protective, or mechanical properties. Investors care because these tiny layers are central to products like displays, solar panels, sensors, and protective coatings; improvements can cut costs, boost performance, or enable new products the way a better paint or adhesive can change what an object can do.

rohs-compliant regulatory

"These include ... RoHS-compliant, halogen-free, and Vishay Green"

RoHS-compliant means a product meets rules that limit or ban certain hazardous chemicals in electrical and electronic equipment, ensuring the item does not contain those restricted substances above set limits. For investors this matters because compliance affects a company's ability to sell in regulated markets, avoid fines and recalls, and manage production costs and supply-chain risks—similar to a food product following a recipe that omits banned ingredients to stay sellable and safe.

phased-array radar technical

"data link arrays; and phased-array radar systems"

A phased-array radar is a radar system made of many small antenna elements whose signals are timed so the detection beam can be steered electronically instead of by moving parts. Think of it like a choir where changing when each singer starts directs the sound in a particular direction. Investors care because this design offers faster tracking, greater reliability and flexibility, and is central to modern defense, aerospace and telecom products that drive large contracts and long-term revenue.

Offered in a Compact 1817 SMD Package, the Device Operates From 15 GHz to 20 GHz and Provides Industry-Low Insertion Loss of < 0.5 dB Below 19 GHz

MALVERN, Pa., April 08, 2026 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new 2-way Wilkinson power divider / combiner designed to increase efficiency and save space in aerospace, defense, and high frequency connectivity applications. Operating over a broad 15 GHz to 20 GHz range, the Vishay Sfernice WLKN-000 delivers industry-low insertion loss of < 0.5 dB below 19 GHz in an integrated surface-mount package.

With its wide frequency range and return loss of 10 dB to 15 dB, the device released today simplifies system designs, while reducing required external components to save board space and lower costs. Its compact 1817 package integrates a three-port solution to support both divider and combiner functionality, streamlining layouts. The device’s low insertion loss enhances system efficiency by minimizing power dissipation throughout the signal path.

Unlike narrowband or resistor-based solutions, the WLKN-000 offers high output to output isolation — < 20 dB at the center frequency — to minimize crosstalk, protect downstream amplifiers during combining, and preserve stable performance across parallel RF paths. In addition, the device offers excellent matching characteristics across the entire operating band.

A wide temperature range of -55 °C to +155 °C ensures reliable performance in challenging conditions across a variety of applications. These include automotive ADAS and radio transceivers; LEO satellites and base station terminals; 5G / 6G connectivity; drones; weapons guidance systems; payload systems; data link arrays; and phased-array radar systems.

RoHS-compliant, halogen-free, and Vishay Green, the WLKN-000 is built on thin film technology. The device can be customized based on customer specifications for frequency band, return loss, insertion loss, case size, and more. HFSS-encrypted models are also available.

Samples and production quantities of the WLKN-000 are available now, with lead times of 20 weeks.
