Qorvo QPF4001EVBV1

Overview

QPF4001EVBV1 from Qorvo is an evaluation board designed to demonstrate and validate the RF front-end module QPF4001, a 5 GHz Wi-Fi 6 (802.11ax) power amplifier with integrated LNA and T/R switch for wireless access points and residential gateways. It supports 80 MHz channel bandwidth, delivers +27 dBm POUT at 3.5% EVM, and operates from a single 5 V supply.

For engineers reviewing the QPF4001EVBV1 datasheet, pinout, applications, or equivalent options, this board enables rapid characterization of output power, ACPR, EVM, and receive sensitivity under real-world 5 GHz OFDMA and MU-MIMO conditions using standard test equipment and Qorvo's reference firmware.

Technical Context

The QPF4001EVBV1 implements a fully populated, impedance-matched layout optimized for the QPF4001 RF FEM, including calibrated 50 Ω SMA connectors for RF IN/RF OUT, integrated bias tees, and on-board DC-DC converter circuitry supporting 5 V input with regulated 3.3 V and 1.8 V rails for auxiliary logic. It features jumpers for TX/RX mode selection and external gain control.

Designed for IEEE 802.11ax compliance testing, the board includes thermal vias and copper pour for thermal management during high-duty-cycle OFDM transmission, and supports both continuous wave (CW) and modulated signal testing per FCC/ETSI regulatory requirements.

FAQ

What is the primary function of the QPF4001EVBV1?

The QPF4001EVBV1 is an evaluation board specifically built to characterize the QPF4001 RF front-end module. It provides calibrated RF paths, regulated power delivery, and mode-selectable operation to verify transmit output power, receive sensitivity, linearity, and spectral mask compliance under Wi-Fi 6 5 GHz operating conditions. The QPF4001EVBV1 does not operate as a standalone transceiver.

Does the QPF4001EVBV1 support both 802.11ax and legacy 802.11ac signals?

Yes, the QPF4001EVBV1 supports both standards because it hosts the QPF4001, which is specified for 802.11ax but maintains backward compatibility with 802.11ac modulation schemes. Its RF path and biasing are optimized for OFDMA and MU-MIMO waveforms, and the QPF4001EVBV1 has been validated with both 256-QAM and 64-QAM signals across 20/40/80 MHz channels.

Can the QPF4001EVBV1 be used for conducted immunity or radiated emissions testing?

No - the QPF4001EVBV1 is not certified or constructed for EMC pre-compliance testing. It lacks shielding, filtered I/O, and controlled emission paths required for such measurements. It is intended strictly for conducted RF parameter validation (e.g., EVM, ACPR, gain, NF) using lab-grade instruments. For emissions work, users must integrate the QPF4001 into a system-level PCB with proper enclosure and filtering.

Is the QPF4001EVBV1 compatible with Qorvo's QPG6100 or QPG6200 SoCs?

The QPF4001EVBV1 is not directly interfaced with QPG6100/QPG6200 SoCs out-of-the-box. It requires external baseband control (e.g., GPIO, SPI) and clock synchronization. While the QPF4001 FEM is architecturally compatible with those SoCs, the QPF4001EVBV1 board itself provides only RF and power interfaces - no digital host interface or firmware stack is included on the board.

What documentation accompanies the QPF4001EVBV1?

The QPF4001EVBV1 ships with the QPF4001 Evaluation Board User Guide (Qorvo document QAN-000129), which includes schematic diagrams, bill of materials, layout files, test setup instructions, and measured S-parameter data. No source code or driver packages are provided - the QPF4001EVBV1 is a hardware-only validation platform.
