【GaN HEMT Evaluation Board】

GaN technology has become the cornerstone of modern high-performance RF power amplification due to its high power density, high efficiency, and high operating frequency characteristics. Qorvo's GaN HEMT evaluation board provides engineers with an excellent platform to explore the potential of this advanced technology.

QPD0011EVB1: An Evaluation Platform Designed Specifically for GaN HEMTs

The QPD0011EVB1 is an evaluation board specifically designed to assess the performance of GaN HEMT transistors. Its core design is optimized for the 3.3 GHz to 3.6 GHz operating band, which holds significant applications in specific satellite communications, radar, and point-to-point radio systems. This evaluation board integrates the transistor, optimized input/output matching networks, bias circuitry, and standard SMA connectors into a single unit. Engineers can immediately connect test equipment to directly measure key metrics such as transistor gain, output power, efficiency, and linearity—eliminating the need to design complex PCB layouts and matching circuits from scratch.

【Limiter Evaluation Board】

In scenarios with high-intensity signals, such as radar and electronic warfare, sensitive low-noise amplifiers (LNAs) and receiver front ends are highly susceptible to damage from unexpected strong signals or interference. The limiter's role is to allow signals to pass with low loss under normal conditions while rapidly limiting their amplitude when encountering high-power signals, acting as the “guardian” of the receive chain. Qorvo's limiter evaluation board makes protection circuit design intuitive.

TGL2205 Series Evaluation Solution: Balancing Protection and Performance

The TGL2205 is a high-power, broadband limiter MMIC based on GaAs technology. Its core feature is the elimination of DC bias requirements, simplifying system design. It achieves excellent insertion loss below 0.5 dB across the 1 to 6 GHz frequency range, handles pulse power up to 100 watts, and maintains low leakage power. Although the search results do not directly list an evaluation board model, following Qorvo's product convention, such core MMICs typically have corresponding evaluation modules available. Engineers can utilize these modules to directly test the actual protection effectiveness against back-end devices and the signal loss introduced by the MMIC itself in applications such as commercial/military radar and electronic warfare receivers.

【Ultra-Wideband (UWB) Evaluation Boards】

Ultra-wideband technology plays a critical role in centimeter-level indoor positioning and high-speed short-range data transmission due to its exceptional time resolution, low power consumption, and strong anti-interference capabilities. Qorvo's UWB evaluation boards provide turnkey solutions for rapid development of such applications.

DWM3000EVB: Rapid Development Platform for UWB RF Modules

The DWM3000EVB is a highly integrated evaluation board centered around the DWM3000 Ultra-Wideband transceiver module. Fully compliant with the IEEE 802.15.4 standard, this module operates within the 6.25 GHz to 8.25 GHz UWB spectrum and is optimized for implementing precise Real-Time Location Systems (RTLS). The evaluation board typically integrates antennas, all necessary RF circuitry, and microcontroller interfaces. Developers can directly evaluate ranging accuracy, communication rates, and multipath interference performance via software APIs with minimal involvement in underlying RF design, accelerating application development for scenarios such as asset tracking, smart access control, and industrial navigation.
