10W 830-960MHz GaN RF Signal Blocker Jammer with Circulator, SMA-Female for EU LoRa 868MHz & US 915MHz IoT Networks Shielding

Product Description

This 10W GaN RF signal blocker is engineered to deliver reliable, wideband RF interference across the 830–960MHz frequency range, specifically targeting the most widely used IoT communication bands: the EU LoRa 868MHz band and the US 915MHz ISM band. Whether you need to prevent unauthorized data transmission, isolate sensitive areas from wireless leakage, or conduct controlled RF testing, this jammer provides a robust and efficient solution.

This module advanced gallium nitride (GaN) technology.  This translates into a stable 10W output with excellent linearity and ruggedness, even under continuous operation. The result is consistent jamming coverage with minimal signal gaps and reduced heat generation, extending the unit's service life.

A built-in RF circulator is a key differentiator. By directing forward power to the antenna while safely diverting reflected power into an internal load, the circulator protects the GaN amplifier from damage caused by antenna mismatch, open or short circuits, or environmental changes. This makes the jammer far more durable in field conditions and ensures stable performance without frequent maintenance.

Product Features

Product Application

EU LoRa 868MHz – effectively blocks LoRaWAN, Sigfox, and other LPWAN devices operating in the European 868MHz band.
US 915MHz IoT networks – disrupts LoRa, ISM, and proprietary protocols in the 902–928MHz range.
Additional uses – also affects RFID, smart meters, wireless sensors, and legacy 900MHz systems.
