Qorvo QPQ1909EVB-01

Overview

QPQ1909EVB-01 from Qorvo is an assembled evaluation board designed to validate the QPQ1909 Wi-Fi bandedge Bulk Acoustic Wave (BAW) filter in real RF front-end circuits. It supports full-channel 2.4 GHz Wi-Fi operation (2402–2494 MHz), delivers ≤1.5 dB typical insertion loss across Channels 3–12, enables +30 dBm average input power handling, and maintains ≥14 dB return loss at both input and output ports - all critical for regulatory-compliant access point and residential gateway designs.

For engineers reviewing the QPQ1909EVB-01 datasheet, pinout, applications, or equivalent options, this board provides verified RF performance data, calibrated S-parameter measurement points, integrated 50 Ω matching, and direct drop-in compatibility with standard QPQ1909 module footprint (1.4 × 1.2 mm, 5-pad laminate) - enabling rapid validation of bandedge filtering, adjacent-channel rejection, and high-power linearity in 802.11n/ac/ax systems.

Technical Context

The QPQ1909EVB-01 implements the QPQ1909 BAW filter in a controlled 4-layer FR-4 PCB layout with 50 Ω microstrip routing, SMA edge-mount connectors on input/output, and dedicated ground vias aligned to the QPQ1909's three GND pads (Pins 2, 3, 5). It replicates the reference design from Qorvo's datasheet Figure 7 (Applications Circuit), preserving the exact impedance-matching network and decoupling configuration used for production qualification.

Test-ready features include solder jumpers for optional DC blocking capacitor bypass, test points for VNA calibration at RF ports, and thermal relief pads optimized for +90 °C continuous operation. The board is validated for use with 802.11n MCS0 signals (10 dB PAR) and supports full regulatory band testing across Channels 1–14 without external tuning components.

FAQ

What is the primary purpose of the QPQ1909EVB-01 evaluation board?

The QPQ1909EVB-01 evaluation board is designed to accelerate RF validation of the QPQ1909 BAW filter in real-world Wi-Fi 2.4 GHz front-end designs. It provides calibrated SMA interfaces, verified 50 Ω routing, and exact replication of Qorvo's reference circuit - allowing engineers to measure insertion loss, return loss, and adjacent-band rejection without custom PCB prototyping. The board directly supports regulatory testing for Channels 1–14 and confirms +30 dBm power handling per the QPQ1909 datasheet.

Does the QPQ1909EVB-01 require external bias or control signals to operate?

No, the QPQ1909EVB-01 is a passive evaluation platform - the QPQ1909 filter itself requires no DC bias, enable signal, or control interface. All five terminals (INPUT, OUTPUT, and three GND pads) are routed as specified in the QPQ1909 datasheet Pin Configuration table. The board operates purely as an RF pass-through path, with internal 50 Ω matching eliminating need for external matching networks during characterization of the QPQ1909 device.

Can the QPQ1909EVB-01 be used to evaluate other Qorvo BAW filters?

No - the QPQ1909EVB-01 is mechanically and electrically optimized exclusively for the QPQ1909. Its 1.4 × 1.2 mm land pattern, pad geometry, via placement, and microstrip trace width match only the QPQ1909's 5-pad laminate package. Substituting other filters (e.g., QPQ1908 or QPQ2201) would cause impedance mismatch, degraded return loss, and invalid RF measurements due to differing terminal layouts and internal matching.

What RF test equipment is recommended for use with the QPQ1909EVB-01?

A vector network analyzer (VNA) with frequency coverage up to 3 GHz and calibrated S-parameter measurement capability is required. Qorvo specifies that the QPQ1909EVB-01 supports full 2-port S-parameter characterization (S11, S21, S12, S22) using the onboard SMA connectors. For power-handling validation, a signal generator with 802.11n-compliant OFDM waveform (10 dB PAR) and a power meter or spectrum analyzer are recommended - all referenced to the QPQ1909EVB-01's defined test conditions in the QPQ1909 datasheet.

Is the QPQ1909EVB-01 RoHS and lead-free compliant?

Yes - the QPQ1909EVB-01 uses RoHS-compliant materials and lead-free assembly processes. The QPQ1909 filter mounted on the board meets EU Directive 2011/65/EU (RoHS) and 2015/863/EU amendments, including halogen-free, antimony-free, TBBP-A-free, and SVHC-free specifications. PCB fabrication and soldering follow IPC/JEDEC J-STD-020 MSL Level 3 guidelines, with peak reflow temperature rated at 260 °C for lead-free processes.
