Product details
Overview
AFRX5G272T4 from NXP Semiconductors is an integrated RF front-end receiver module for TD-LTE and 5G mMIMO base station applications, featuring 2300–2690 MHz operation, 33.0 dB Rx gain, 1.2 dB noise figure at 2500 MHz, and 5 V supply with 1.8 V JEDEC-compliant T/R control logic.
For engineers reviewing the AFRX5G272T4 datasheet, AFRX5G272T4 pinout, AFRX5G272T4 application, or AFRX5G272T4 equivalent, key selection criteria include Tx/Rx mode switching speed (<1.0 µs gain settling), robust 39.0 dBm short-term Tx port power handling, 55 dB reverse isolation, and compatibility with QFN 6×6 mm PCB footprints.
Technical Context
The AFRX5G272T4 integrates a T/R switch, two-stage LNA, and internal 100 kΩ pulldown on the T/R pin to enable fast mode transitions between antenna-to-Rxout (Rx) and antenna-to-external-termination (Tx). It operates without external matching in 50 Ω systems across its full 2300–2690 MHz band.
In Rx mode, the device delivers 33.0 dB gain and 1.2 dB NF while consuming 500 mW; in Tx mode, it provides –0.75 dB insertion loss and handles up to 39.0 dBm average incident power for 10 seconds, with idle LNA current minimized to reduce system-level power draw.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 2300–2690 MHz: Full-band operation for TD-LTE and 5G mMIMO base station receive paths. |
| Rx Gain | 33.0 dB typical: Enables high-sensitivity signal capture before baseband digitization. |
| Noise Figure | 1.2 dB at 2500 MHz: Minimizes degradation of system SNR in dense multi-antenna deployments. |
| Reverse Isolation | 55 dB: Prevents Tx leakage from coupling into Rx path during simultaneous TDD operation. |
| Tx Port Robustness | 39.0 dBm avg. (10 sec): Supports transient LTE/5G burst power without damage or performance shift. |
| Control Interface | 1.8 V JEDEC-compliant T/R logic: Ensures interoperability with standard FPGA/GPIO voltage levels. |
| Supply Voltage | 5 V DC: Simplifies power architecture by eliminating need for additional bias rails beyond main system rail. |
Pinout & Package
AFRX5G272T4 uses a compact 6.2 mm × 6.2 mm LGA package compatible with QFN 6 × 6 mm land patterns, enabling drop-in layout reuse in high-density mMIMO radio modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3–5, 7, 9–13, 15–16, 18, 20–21 | GND | RF and DC ground reference planes; multiple pins ensure low-inductance return paths for both Tx and Rx signals. |
| 2 | ANT | Shared antenna port; routes RF energy to internal LNA in Rx mode or to external 50 Ω termination in Tx mode. |
| 6 | N.C. | No internal connection; must be left unconnected per design-no pull-up/down or routing required. |
| 8 | VDD | 5 V DC bias input; requires local decoupling (e.g., 10 µF + 10 pF per NXP app circuit) to suppress supply noise. |
| 14 | Rxout | Differential-capable single-ended RF output; connects directly to baseband ADC or mixer input with no external matching. |
| 17 | T/R | Digital control input with integrated 100 kΩ pulldown; high = Rx mode, low = Tx mode; supports 1.8 V logic timing. |
| 19 | Tx/TERM | 50 Ω-terminated RF path; requires external 50 Ω resistor to ground to absorb Tx energy during transmit cycles. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated T/R Switch + Dual-Stage LNA | Eliminates discrete switch/LNA cascading, reducing BOM count and board area in 64T64R mMIMO arrays. |
| 50 Ω Matched I/O Ports | Removes need for external matching networks-reduces tuning complexity and improves repeatability across production units. |
| Fast Mode Switching | <1.0 µs Rx gain settling enables tight TDD guard-band timing in sub-6 GHz 5G NR frame structures. |
| Thermal Robustness | Rated for case temperatures from –40°C to +105°C, supporting outdoor macro and distributed unit deployments. |
| ESD Protection | HBM Class 2 (2 kV) and CDM Class C3: Meets industrial handling requirements without added protection circuitry. |

FAQ
What is the operating frequency range of the AFRX5G272T4?
The AFRX5G272T4 operates from 2300 MHz to 2690 MHz, covering key TD-LTE and 5G NR bands including Band 38, Band 40, and n41. This range is validated per NXP's electrical characteristics table at 2500 MHz with typ values for gain, NF, and IIP3-all specified across the full band in functional block and application notes.
Does the AFRX5G272T4 require external impedance matching?
No, the AFRX5G272T4 features fully 50 Ω matched ANT, Rxout, and Tx/TERM ports. NXP's datasheet explicitly states "50 ohm operation with no external matching" and confirms this in the application circuit (Figure 3), which uses only decoupling capacitors and no matching components on RF paths.
What is the function of the N.C. pin (Pin 6) on the AFRX5G272T4?
Pin 6 on the AFRX5G272T4 is designated N.C. (No Connection) in Table 6 of the NXP datasheet. It has no internal connection and must remain unconnected-neither tied to ground nor routed-to avoid unintended parasitic coupling or thermal stress on the die.
How does the AFRX5G272T4 handle thermal stress in outdoor base station deployments?
The AFRX5G272T4 is rated for case operating temperatures from –40°C to +105°C and junction temperatures up to 150°C. Its LGA package provides efficient thermal conduction to the PCB, and the 500 mW Rx power consumption is optimized to limit self-heating-validated in NXP's thermal derating curves and reliability testing per JESD22-A113.
Is the AFRX5G272T4 pin-compatible with earlier NXP Airfast RX modules like AFRX5G271?
No, the AFRX5G272T4 is not pin-compatible with AFRX5G271. Pin counts, pin functions (e.g., dedicated Tx/TERM vs. shared Tx/Rx), and package dimensions differ-AFRX5G272T4 uses 21-pin LGA while AFRX5G271 uses different pinout and footprint per NXP's separate datasheets and ordering information tables.
