NRF2402G-REEL

Overview

The NRF2402G-REEL is a single-chip RF transmitter manufactured by Nordic Semiconductor ASA, designed for the 2.4 GHz ISM band. It operates on a supply voltage range of 1.9 V to 3.6 V and supports data rates up to 1 Mbps using GFSK modulation. The component features an output power of 4 dBm and consumes approximately 10 mA during operation. Packaged in a 16-VQFN (4 mm x 4 mm) exposed pad with SMD/SMT installation style, it functions within a temperature range of -40°C to +85°C. The device utilizes a 3-wire interface and is RoHS compliant.

Feature Summary

• Integrates a complete radio transmitter solution in a compact CMOS process
• Supports GFSK modulation for reliable short-range wireless communication
• Features low power consumption suitable for battery-operated applications
• Includes shockBurst protocol support for efficient packet handling

Applications

• Home automation systems
• Remote sensing devices
• Keyless entry systems (RKE)

Procurement Notes

Verify component status carefully as the NRF2402G series has been officially declared obsolete by Nordic Semiconductor. Confirm availability through authorized distributors or secondary market suppliers, noting that new production units may be limited. Ensure compatibility with existing PCB layouts due to the specific 16-VQFN package dimensions and pinout configuration before finalizing procurement decisions.

Selection Notes

Select this component for simple point-to-point transmission needs in the 2.4 GHz band where low cost and minimal external components are prioritized. Consider the discontinued status when planning long-term product lifecycles. Evaluate alternative Nordic Semiconductor transmitters if future supply chain stability is required. Ensure design accommodates the specific thermal and electrical characteristics of the QFN-16 package.

Part Context

The NRF2402G belongs to the nRF240X family of wireless components from Nordic Semiconductor. These parts were among the first manufactured using a 0.18µm pure CMOS process. The series focuses on providing affordable, low-power solutions for short-range wireless applications. The 'G' suffix typically denotes specific packaging or revision details within the broader nRF2402 product line.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is marked obsolete, direct replacements should be identified through Nordic Semiconductor's current portfolio or equivalent third-party transmitters meeting similar 2.4 GHz GFSK specifications.
