【RF Front End Module Evaluation Board】

RF Front End Module integrates multiple functions—including power amplifiers (PA), LNA, switches, and filters—into a single unit, serving as the core component for achieving device miniaturisation. Its evaluation board provides the optimal starting point for verifying the module's overall performance and conducting joint debugging with the main platform.

For instance, the QPF4659EVB, designed for the future Wi-Fi 7 standard, features the corresponding QPF4659 FEM supporting the full 5.925–7.125 GHz (6 GHz) band. This evaluation board enables engineers to directly test the module's linearity, efficiency, and thermal performance under high-throughput, wide-band operation – critical for designing premium routers supporting 320MHz channel bandwidth and MLO technology.

For the more mainstream Wi-Fi 6 market, FEMs such as the QPF4228—though their dedicated evaluation board models may not be explicitly listed in search results—typically provide reference evaluation circuits and layouts within their datasheets. When evaluating such modules, particular attention should be paid to their dynamic EVM performance in the 2.4GHz band, as this directly impacts data throughput under high-order modulation schemes such as 1024-QAM.

【RF Filter Evaluation Board】

As spectrum resources become increasingly congested, filters remain indispensable for suppressing out-of-band interference and ensuring signal purity. Qorvo leads in BAW filter technology, with its evaluation boards enabling designers to directly compare performance differences between solutions.

QPQ5601 evaluation board exemplifies this capability, designed for assessing Wi-Fi BAW filters operating within the 5945-7125MHz band. All RF ports are routed to SMA connectors, enabling engineers to conveniently measure critical metrics such as insertion loss, return loss, and out-of-band rejection using a network analyser. This proves decisive for designing equipment supporting the 6GHz band, enabling avoidance of interference with existing 5GHz signals.

Within the 5G infrastructure domain, Qorvo's QPQ3550 compact BAW filter addresses the spatial constraints inherent in 5G mMIMO systems. Although details of its dedicated evaluation board are not elaborated in search results, it is anticipated that such boards will demonstrate how it achieves insertion loss below 2dB and power handling capability up to 30dBm within an extremely compact 2.0x1.6mm package.

【RF Transistor Evaluation Board】

RF Transistor offer the highest flexibility and performance optimisation potential for system design. Their evaluation boards are typically employed for early prototyping and performance boundary exploration.

For instance, the QPC9314EVB corresponds to the QPC9314, an RF front-end chip operating at 2.3-2.7GHz. Its evaluation board facilitates measurement of its up to 33dB gain and excellent noise figure. This is crucial for designing base station receive channels demanding exceptionally high sensitivity.

Additionally, Qorvo's QPA9862 broadband pre-driver amplifier, a key component for 5G mMIMO systems, supports instantaneous bandwidths up to 600MHz and 38dB gain. Its evaluation board will focus on verifying linearity under wideband signals and stability at elevated operating temperatures, providing valuable reference for addressing thermal challenges in large-scale antenna arrays.
