RFPA5208TR13 – 2.4GHz Wi-Fi Power Amplifier 40dB Gain

Basic Product Information

Part Number: RFPA5208TR13

Core Electrical Parameters

Core Features & Advantages

The RFPA5208TR13 is Qorvo’s 2.4 GHz Wi-Fi power amplifier module optimized for 802.11b/g/n/ac systems — integrating a three-stage PA, regulator, and power detector in a 4 x 4 mm laminate package. Note: This product has been discontinued (EOL September 2023); new designs should consider the alternatives listed below.

• Primary Function: 2.4 GHz three-stage Wi-Fi power amplifier with 40 dB gain, +28 dBm 802.11n output power, integrated regulator and power detector, input/output matched to 50 Ω, in a 10-pin 4 x 4 mm laminate MCM package.
• Advantages:
  • Fully Matched 50 Ω I/O — Zero External RF Matching: The integrated input and output 50 Ω matches eliminate the need for external matching networks, tuning components, or RF engineering expertise at the PCB design stage. This reduces BOM count, PCB area, and manufacturing variability — the PA can be placed directly in the RF signal path with only DC decoupling and bias resistors.
  • Integrated PA + Regulator + PDET — Minimal BOM: The on-chip regulator simplifies bias control (single Vcc supply), while the integrated power detector coupler provides real-time output power monitoring for closed-loop power control and ALC (Automatic Level Control). This integration reduces external component count from ~15 discrete parts (PA + bias + detector) to typically 5–7 passive components.
  • 40 dB Gain — Eliminates Driver Stage: The three-stage architecture delivers 40 dB of small-signal gain — sufficient to amplify the 0–5 dBm transceiver output directly to +28 dBm without an intermediate driver amplifier. This single-stage RF chain simplifies layout, reduces current consumption, and minimizes inter-stage matching complexity.

Typical Application Scenarios

• Industry: Wireless Infrastructure / Consumer Networking / Industrial Wireless
• Equipment: Wi-Fi routers, wireless access points, range extenders, gateways, microcells, CPE
• Use Cases:
  • 2.4 GHz Wi-Fi Router/AP RF Front-End: The RFPA5208TR13 amplifies the 2.4 GHz transceiver output to +28 dBm for 802.11n MCS7 or +26 dBm for 802.11ac MCS8 — delivering reliable wall-penetrating range in residential and enterprise access points. The integrated PDET enables dynamic power calibration to maintain EVM compliance across temperature and voltage variations.
  • Wi-Fi Range Extender / Repeater: The high gain and integrated matching make the RFPA5208TR13 ideal for compact range extender designs where PCB area and BOM cost are critical. The 50 Ω matched interface connects directly to the transceiver and antenna switch without external matching, reducing design cycle time and manufacturing test complexity.
  • Industrial 2.4 GHz Wireless Link: In industrial monitoring and control applications, the +28 dBm output power provides extended range for point-to-point 2.4 GHz links in factory floors and warehouses. The -30 dB EVM ensures reliable high-order modulation (64-QAM, 256-QAM) for maximum throughput in noisy RF environments.
