MDPB-ST

The SZMID - MDPB-ST is a high-performance portable cellphone jammer designed for both indoor and outdoor use, offering effective signal blocking to protect communication security and privacy in designated areas. Utilizing advanced wideband white noise interference technology, this device efficiently blocks all common mobile communication signals, including 2G, 3G, 4G, 5G, and WiFi (2.4GHz + 5.8GHz). Its modular design provides high integration, enabling flexible customization of frequency bands ranging from 80MHz to 6000MHz to meet specific user requirements.

Equipped with imported power amplifiers and ICs, the MDPB-ST offers robust performance and stability. Each module is isolated with shielding boxes to prevent interference, while standing wave protection technology ensures durability, even when unloaded. The dual power supply system allows the device to switch to battery mode, providing 1.5 to 2 hours of continuous operation. The digital display shows real-time voltage and battery status, giving users full control over the device’s performance.

For extended use, the device features a high-efficiency cooling system, utilizing an aluminum alloy heat sink and two high-power fans that maintain the operating temperature below 55°C, ensuring stable long-term functionality. Despite its powerful performance, the MDPB-ST is designed for portability, with a lightweight structure and simple plug-and-play operation using a built-in 3dBi high-gain antenna.

Ideal for secure environments requiring reliable signal blocking, this device guarantees military-grade quality, offering peace of mind in sensitive applications.
