NRF24E2G

Overview

The NRF24E2G is a radio transmitter manufactured by Nordic Semiconductor ASA, designed for operation in the 2.4 GHz industrial, scientific, and medical (ISM) band. It utilizes Gaussian Frequency Shift Keying (GFSK) modulation to achieve data rates up to 1 Mbps with an output power of 0 dBm. The device operates on a supply voltage ranging from 1.9 V to 3.6 V and draws 13 mA during transmission. It is housed in a 36-VFQFN package with an exposed pad, measuring 6x6 mm, and supports surface-mount installation. The component functions as a standalone RF transmitter without integrated baseband processing.

Feature Summary

• Integrates a GFSK modulator for reliable wireless signal transmission at 2.4 GHz.
• Supports direct PCB trace antenna integration for compact system design.
• Operates within a wide temperature range suitable for diverse environmental conditions.

Applications

• Radio game controllers
• Wireless peripheral devices
• Low-power consumer electronics

Procurement Notes

Verify current availability status as the part may be subject to end-of-life restrictions or limited distribution channels. Confirm that the specific package variant matches the required 36-VFQFN footprint and pinout configuration for the target PCB layout. Ensure compliance with RoHS3 specifications and check for any product change notices affecting manufacturing or sourcing.

Selection Notes

Select this component when a dedicated transmitter solution is required rather than a full transceiver. Consider the 0 dBm output power and 1 Mbps data rate against system range and throughput requirements. Evaluate the need for external baseband control since the chip lacks integrated MCU capabilities compared to other Nordic nRF series products.

Part Context

The NRF24E2G belongs to the nRF24 family of wireless transceivers developed by Nordic Semiconductor. While many parts in this series integrate both receiver and transmitter functionalities with embedded microcontrollers, the NRF24E2G is specifically configured as a transmitter-only device. This specialization allows for simplified circuit designs in applications where bidirectional communication is handled by separate components.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult Nordic Semiconductor's official obsolescence notices or contact authorized distributors for potential alternative recommendations based on specific application constraints.
