Key Terms

rf, microwave, millimeter-wave, hermetic packaging

4 terms

rf technical

"thin film submount platform, designed to support next-generation optical transceivers, RF modules, and advanced"

rf (commonly written r_f) denotes the risk-free rate — the theoretical return on an investment with no chance of loss, often used as a baseline for valuing other assets. Investors use it like a yardstick: returns above this number compensate for extra risk, so it helps price stocks, bonds and option valuations and guides decisions about whether higher-return opportunities justify their added risk. Think of it as the safe deposit box interest rate against which riskier bets are measured.

microwave technical

"low loss thin film interconnects support microwave and millimeter-wave applications"

Microwave describes a band of electromagnetic waves with wavelengths shorter than radio waves and longer than infrared, used for wireless links, radar, satellite and heating in kitchen appliances. For investors, microwave technology matters because it underpins products and services—from telecom networks and defense systems to consumer goods—so shifts in demand, supply chains, regulation, or component costs can affect revenues and profitability much like a highway determines how fast goods can move.

millimeter-wave technical

"low loss thin film interconnects support microwave and millimeter-wave applications"

Millimeter-wave is a band of radio frequencies with very short wavelengths—about one to ten millimeters—used for extremely fast, short-range wireless transmission. Think of it as a higher-pitched radio signal that can carry a lot more data but doesn’t travel as far or through walls as well as lower-frequency signals. Investors care because millimeter-wave technology underpins high-speed wireless networks, radar and sensors, and touches telecom equipment, semiconductor suppliers, and infrastructure spending, so its adoption can drive revenue and regulatory decisions.

hermetic packaging technical

"combined wire bond and SMT processes, and hermetic packaging solutions."

Hermetic packaging is an airtight seal around a product or component that blocks moisture, air and other contaminants—think of it like a vacuum-sealed jar that preserves what’s inside. For investors, it matters because hermetic sealing protects sensitive electronics, medical devices and pharmaceuticals from failure or spoilage, affecting product reliability, regulatory approval, warranty costs and long-term market value.

Submounts Enable Next-Generation Thermal, Optical, and RF Packaging

MALVERN, Pa., April 29, 2026 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today announced its new thin film submount platform, designed to support next-generation optical transceivers, RF modules, and advanced electronic packaging applications requiring high thermal performance, precision alignment, and high frequency signal integrity.

Known for delivering high performance thin film substrates that enable smaller, faster, and more efficient electronic systems in environments where conventional solutions fall short, Vishay uses precision deposition of passive circuit elements and precision machining of advanced ceramic substrates, including aluminum nitride (AlN). This approach delivers superior thermal conductivity, dimensional stability, and electrical performance in demanding environments through the new platform.

The platform is optimized for emerging applications in high speed data communications, including 800G, 1.6T, and 3.2T optical transceivers, where increasing power densities and tighter packaging constraints require enhanced heat dissipation, difficult alignment problems, and low loss interconnect performance. Vishay’s thin film submounts enable designers to improve thermal management at the device level while maintaining precision alignment and signal integrity at high frequencies.

“Next-generation photonics and RF systems push the limits of thermal, mechanical, and electrical performance at the package level,” said Michael Casper, vice president of specialty thin film at Vishay. “Our thin film submount platform provides engineers with a flexible solution that enables high performance without compromising reliability.”

Key Features and Benefits:

• Quick-turn prototyping with high volume production capability from three manufacturing locations
• High thermal conductivity: AlN-based substrates support efficient heat dissipation for high power devices
• High frequency performance: low loss thin film interconnects support microwave and millimeter-wave applications
• Miniaturization: compact, integrated designs support space-constrained modules
• Reduction in manufacturing complexity: pre-deposited AuSn or EPIG and precision machining support difficult manufacturing processes
• Design flexibility: tailored geometries, metallization schemes, and circuit integration support custom designs
  
  

Vishay’s thin film submount platform is proven in a wide range of applications, including laser diode mounting, RF / microwave modules, optical alignment, combined wire bond and SMT processes, and hermetic packaging solutions. The company works closely with customers in defense, space, and high reliability industrial applications to develop designs that meet stringent performance and environmental requirements.
