Product details
Overview
SE2620T-R from Skyworks is a 2.4 GHz ISM band RF front-end module integrating a power amplifier, low-noise amplifier, and SPDT switch for Bluetooth and Zigbee applications. It delivers +20 dBm output power with 3.3 V supply, 35% PAE, and -33 dBc EVM at 11 Mbps DSSS. Used in wireless sensor nodes and BLE peripherals.
For engineers reviewing the SE2620T-R datasheet, SE2620T-R pinout, SE2620T-R application, or SE2620T-R equivalent, key selection criteria include integrated Tx/Rx switching, 2.4 GHz ISM band operation, +20 dBm POUT, 35% PAE, and QFN-16 package compatibility with PCB layout constraints.
Technical Context
The SE2620T-R integrates a 2.4 GHz PA, LNA, and single-pole double-throw (SPDT) switch in one die-on-package configuration. It supports 802.15.4 and Bluetooth BR/EDR modulation schemes with integrated bias control and on-chip matching networks.
Operation requires only three external components: DC blocking capacitors and a single RF choke. The device uses standard CMOS-compatible control logic (1.8 V logic interface) and features integrated harmonic filtering meeting FCC/ETSI spectral mask requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF front-end module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Qorvo QPF4206 | Higher POUT (+22 dBm), wider 2.4–2.5 GHz range, but requires 5 V supply and separate LNA enable control. | Better for mains-powered access points; less suitable for coin-cell designs due to voltage and control complexity. | Select QPF4206 only if +22 dBm and 5 V infrastructure exist; SE2620T-R remains optimal for 3.3 V battery systems. |
| Silicon Labs BGX13P | Integrated SoC (ARM Cortex-M4 + BLE radio + FEM), no external RF routing needed, but fixed protocol stack and non-upgradable RF calibration. | Best for turnkey BLE end-products; not suitable for custom PHY or multi-protocol (Zigbee + BLE) designs requiring discrete FEM flexibility. | Choose BGX13P for rapid BLE-only development; retain SE2620T-R when protocol agility, external transceiver choice, or Zigbee support is required. |
Compared with QPF4206 and BGX13P, the SE2620T-R uniquely balances 3.3 V operation, discrete transceiver interfacing, and dual-protocol (BLE/Zigbee) readiness-making it the preferred FEM for flexible, battery-optimized 2.4 GHz IoT node designs where RF architecture control is essential.

FAQ
What is the operating frequency range supported by the SE2620T-R?
The SE2620T-R operates across the full 2400–2483.5 MHz ISM band. This range fully supports Bluetooth Basic Rate/Enhanced Data Rate, Bluetooth Low Energy, and IEEE 802.15.4 (Zigbee, Thread) protocols without external tuning components. Its internal matching network is optimized for this band, ensuring consistent +20 dBm output and <−33 dBc EVM performance across all channels.
Does the SE2620T-R require external matching components for 50 Ω antenna interface?
No, the SE2620T-R does not require external matching components for its 50 Ω antenna interface. The ANT pin is internally matched to 50 Ω across the 2.4 GHz ISM band. Only a DC-blocking capacitor and optional π-filter for additional harmonic suppression are recommended per Skyworks Application Note AN-1129. This simplifies PCB layout and reduces bill-of-materials cost compared to discrete RF solutions.
What logic voltage levels are compatible with the SE2620T-R control pins?
The SE2620T-R control pins (EN and TXRX) accept 1.8 V CMOS logic levels, with VIH = 1.2 V min and VIL = 0.6 V max. These pins are directly compatible with 1.8 V GPIOs found on Nordic Semiconductor nRF52840, nRF5340, and Texas Instruments CC2652R microcontrollers. No level-shifting circuitry is required, reducing design complexity and board area.
How does the SE2620T-R manage thermal performance in compact IoT enclosures?
The SE2620T-R uses a thermally enhanced 3 mm × 3 mm QFN package with an exposed EP pad. When mounted with ≥4 thermal vias connecting the EP to an internal ground plane, it sustains continuous +20 dBm operation at 3.3 V with junction temperatures below 105°C at 25°C ambient. Skyworks recommends a minimum 10 mm² copper pour under the EP for optimal conduction cooling in sealed enclosures.
Can the SE2620T-R be used in both Bluetooth and Zigbee systems simultaneously?
The SE2620T-R supports both Bluetooth and Zigbee physical layers because it operates across the entire 2.4 GHz ISM band and provides identical RF performance (POUT, EVM, NF) for GFSK and O-QPSK modulations. However, true simultaneous operation requires an external transceiver capable of dual-protocol baseband processing-the SE2620T-R itself serves as the shared RF front-end for either protocol, not both concurrently on a single chip.
