N542AS High‑Power, Long‑Range Sub‑1 GHz Wireless Module

Based on Silicon Labs Si4463 | Up to +33 dBm Output | 8 km Range

1. Product Overview

The N542AS is a high‑performance, long‑range wireless module designed for demanding IoT applications where distance and link reliability are critical. Integrating the robust Silicon Labs Si4463 transceiver with an external high‑power amplifier, it delivers an exceptional +33 dBm output power, enabling reliable communication over distances up to 8 kilometres line‑of‑sight.

Supporting key Sub‑1 GHz ISM bands (169, 433, 868, 915 MHz), it combines extreme range with the ultra‑low sleep current of the Si4463 (only 0.1 µA), making it ideal for battery‑operated, wide‑area sensor networks and telemetry systems.

5. Product Line Positioning & Selection Guide

The N542AS sits at the top of our performance‑centric series, offering the best balance of power, range, and system complexity.

6. Why Choose the N542AS?

The N542AS is the pragmatic choice for engineers who need more range than a basic module can provide, but want to avoid the complexity, cost, and higher power consumption of a full 2‑watt solution. It effectively solves the problem of covering large farms, industrial campuses, or suburban networks, offering a significant range boost over +20 dBm modules while remaining easier to integrate and power than its +33 dBm counterpart.
