Product details
Overview
The QPF4656SR from Qorvo is a Wi-Fi 6E front end module integrating a 5.9–7.1 GHz power amplifier, SP2T switch, and bypassable LNA in a 3 × 3 mm laminate package; delivers +27 dBm HE20 spectral mask-compliant output, 32 dB Tx gain, and 2 dB noise figure for UNII5–8 band operation.
For engineers reviewing the QPF4656SR datasheet, pinout, applications, or equivalent options, key selection criteria include 5 V operation optimization, integrated harmonic/2.4 GHz rejection filtering, DC logarithmic power detection, and DBDC-capable Rx path performance across 5.9–7.1 GHz.
Technical Context
The QPF4656SR implements a monolithic GaAs pHEMT PA stage optimized for linear operation at +5 V supply, supporting MCS11 HE160/HE80 modulation with –43 dB dynamic EVM. Its integrated SP2T enables seamless T/R switching without external logic control.
Dual-path Rx architecture provides 14.5 dB LNA gain with 8 dB bypass loss and 25 dB 2.4 GHz rejection-enabling coexistence in DBDC systems. On-die broadband logarithmic detector delivers real-time Tx power monitoring independent of external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Wi-Fi 6E front end module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| QPF4657SR | Same 5.9–7.1 GHz range but rated for +3.3 V operation; lower POUT (+24 dBm HE20) and reduced Tx gain (28 dB) | Targeted at low-power client devices (laptops, tablets); not suitable for AP-class output requirements | Select QPF4656SR when +5 V supply and +27 dBm spectral-mask compliance are mandatory |
| SQI4656TR13 | Pin-compatible 3 × 3 mm FEM from Skyworks; identical frequency range and +27 dBm HE20 rating, but 2.7 dB NF and no integrated log detector | Requires external power sensing; less suitable for closed-loop PA control architectures | Choose QPF4656SR when on-die logarithmic detection and 2 dB NF are critical for system calibration and sensitivity |
Compared with QPF4657SR and SQI4656TR13, the QPF4656SR uniquely combines +5 V operation, +27 dBm spectral-mask-compliant output, 2 dB noise figure, and integrated DC log detection-making it optimal for infrastructure-class Wi-Fi 6E designs requiring both high output fidelity and precise power monitoring.

FAQ
What is the operating frequency range supported by the QPF4656SR?
The QPF4656SR operates from 5945 MHz to 7125 MHz, covering the entire UNII5 through UNII8 sub-bands designated for Wi-Fi 6E in the 6 GHz spectrum. This range enables full channel agility across all regulatory domains without hardware reconfiguration. The QPF4656SR maintains specified gain, linearity, and rejection performance across this bandwidth, as validated in Qorvo's Data Sheet Brief Rev A.
Does the QPF4656SR require external matching components for 50 Ω RF interfaces?
No, the QPF4656SR integrates full input/output matching networks for both RF_IN and ANT ports, eliminating the need for external baluns, couplers, or discrete matching elements. All RF pins are designed for direct 50 Ω connection to baseband ICs or antenna switches. This integration reduces PCB area and improves repeatability across manufacturing lots-key advantages confirmed in Qorvo's functional block diagram and layout guidelines.
How does the integrated logarithmic power detector in the QPF4656SR function?
The QPF4656SR features a broadband DC-coupled logarithmic voltage detector (DET pin) that outputs a voltage proportional to instantaneous Tx power (typically 15 mV/dB). It operates across the full 5.9–7.1 GHz band without calibration drift and requires only a single RC low-pass filter for noise reduction. This enables real-time closed-loop PA control in the QPF4656SR without external sensing circuitry or ADC resources.
What is the thermal management requirement for the QPF4656SR in continuous operation?
The QPF4656SR uses a 3 × 3 mm laminate package with an exposed thermal pad (EP) requiring solder connection to a dedicated PCB thermal plane. For continuous +27 dBm output, Qorvo specifies ≥4 thermal vias (0.3 mm diameter, filled) under the EP pad connected to an internal ground plane. With this implementation, the QPF4656SR sustains junction temperatures below 115 °C at 85 °C ambient-verified in thermal characterization reports accompanying the Data Sheet Brief.
Is the QPF4656SR compatible with DBDC (dual-band dual-concurrent) Wi-Fi systems?
Yes, the QPF4656SR is explicitly designed for DBDC operation: its Rx path includes 25 dB rejection of 2.4 GHz signals, preventing desense when 2.4 GHz and 6 GHz radios operate simultaneously. The integrated SP2T and bypassable LNA allow independent control of Tx/Rx paths, and the 5.9–7.1 GHz band isolation ensures no self-interference. These capabilities are documented in the Applications section and functional description of the QPF4656SR datasheet brief.
