JALD-18 Portable SDR Frequency Interference System




Scope of Application: 

Regional Electronic Shielding

Product Characteristics:

Design based on SDR (software defined radio). According to target signal technical characteristics (signal system, modulation mode, parameters), JALD-18 operate the best interference method;

General communication frequency window function;

n System consist of general modulation signal generation unit, broadband high-efficiency power amplifier, high-gain broadband antenna. Unique 5 RF broadband section, save space, reduce power consumption.


Software upgrade. No need to replace hardware, which provide technical support for 5G communication electronic shielding.

n Industrial integrated design, exclusive metal appearance, compact structure. Standing wave/overexcitation and other multiple protection methods design.

n External Lithium battery case (imported plate).

AC/DC power supply after rectification through the batter case. Ammeter and voltmeter assembled for operator to monitor real-time working status.

n One-button operation (optional: external wire control).

Vector fault indicator for quick identification of faulty module information.
