WAVEPIA Co. Ltd. offers a wide range of packaging solutions designed to optimize RF performance, improve thermal efficiency, and support different levels of system integration. Rather than serving only as protective enclosures, the packages that WAVEPIA has developed help control signal behavior, manage heat, and ensure long-term reliability. This approach supports the company’s applications ranging from compact wireless modules to high-power radar and defense systems, with its core work in GaN and GaAs semiconductor device development for high-frequency applications.
For unmatched transistors, WAVEPIA provides packaging options that are structurally optimised based on power and size requirements. The 360BH(S) package is a smaller form-factor design that houses lower-power transistors. Its compact structure reduces board space and simplifies integration, while still providing adequate thermal paths for moderate heat dissipation. This makes it suitable for compact RF modules where space and efficiency are key concerns.
In contrast, the 580BH(S) package is physically larger and built to support higher-power transistors. Its structure allows for better heat spreading and improved thermal conduction, which is critical in high-power RF systems where excess heat can degrade performance or damage the device. This makes it more suitable for applications such as radar transmitters or high-power amplifiers.
Beyond these, the company also develops custom package structures, including multi-chip configurations and versions with integrated temperature sensors. Structurally, these packages allow multiple dies to be mounted within a single enclosure or include embedded sensing elements. This addresses key concerns like real-time thermal monitoring, system protection, and performance optimization under varying operating conditions.
For matched transistor solutions, the company offers its ONE-Package technology, which integrates impedance matching networks directly inside the package. In a typical RF design, external components are required to match the device to a standard 50 ohm system. By embedding this function within the package, the design reduces external circuitry, shortens signal paths, and minimizes mismatch losses. This not only improves RF efficiency but also simplifies the design process, helping engineers reduce development time and avoid tuning complexity.
For MMIC devices, WAVEPIA provides several packaging options, each addressing specific RF and thermal challenges. The MPKG2 ceramic package uses a ceramic base material, which offers high thermal conductivity and mechanical stability. This structure is effective at maintaining consistent RF performance at high frequencies, where signal sensitivity and thermal variation can significantly impact operation. It is commonly used in X-band and higher-frequency systems, including radar and defense applications.
Another structure is the carrier-type leadless package, which removes traditional leads and shortens the electrical path between the chip and the external circuit. This reduced distance helps minimize signal loss and parasitic effects, which become significant at high frequencies. Additionally, its open structure allows heat to dissipate more efficiently, addressing thermal concerns while also enabling more compact system layouts. This makes it suitable for high-frequency, space-constrained RF designs.
Finally, the QFN (Quad Flat No-lead) package is a lead-frame-based structure designed for surface-mount assembly. It provides a balance between electrical performance, thermal efficiency, and cost. The flat, leadless design reduces inductance and improves RF signal integrity compared to traditional lead packages, while also supporting efficient heat transfer through the PCB. This makes it ideal for high-volume, cost-sensitive applications such as commercial wireless devices and RF modules.
WAVEPIA’s packaging solutions are structured to address key challenges in RF design, including signal loss at high frequencies, heat dissipation in high-power systems, and complexity in circuit integration. By offering multiple package types with distinct structural advantages, the company intends to enable designers to select solutions that best align with their performance, size, and cost requirements.
WAVEPIA will be exhibiting at IMS 2026 in Boston next month, where the company will showcase its latest RF power transistor, MMIC, and advanced packaging solutions for high-frequency and high-power applications.
