Description
NRF2401 PA + LNA – Front‑End Power Amplifier & Low‑Noise Amplifier for 2.4 GHz IoT
The NRF2401 is a compact, high‑performance RF front‑end that combines a low‑noise amplifier (LNA) and a power amplifier (PA) in a single 3 mm × 2 mm surface‑mount package. Designed specifically for high‑speed wireless communication, it extends the effective range and improves receiver sensitivity of LoRa, BLE, Zigbee, and GPS modules operating within the 2.3 – 2.6 GHz band with minimal added complexity.
With a broadband frequency range of 2.3 – 2.6 GHz, the NRF2401 delivers a balanced performance: the LNA yields a 20 dB gain while keeping the noise figure under 0.8 dB, and the PA pushes the output power up to +12 dBm. Coupled with an isolation greater than 40 dB between transmit and receive paths, it protects sensitive receivers from self‑interference, making it ideal for dual‑band, dual‑mode GPS and IoT tracking devices running through congested radio spectra.
- Key Spec 1: Frequency Range – 2.3 – 2.6 GHz (wideband 2.4 GHz RF front end)
- Key Spec 2: Gain & Noise Figure – 20 dB gain, NF 0.8 dB (high‑sensitivity LNA)
- Key Spec 3: Output Power & Isolation – +12 dBm PA output, 40 dB isolation Tx→Rx
- Common Use Case: Enhances range and reliability of LoRa, BLE, Zigbee, and GPS receivers in mobile and IoT trackers
