View modelsWhy buyers choose us
Shenzhen R&D, Dongguan Manufacturing
RF design, firmware, and final assembly are all performed in-house, allowing band plans, output power, and mechanical fit to be customized for each project rather than limited to a fixed catalog.
Test data for every shipment
Amplifier modules and jammers are tested for output power, frequency range, and VSWR prior to packaging. Test records accompany bulk shipments for incoming inspection.
Module and system-level supply
Purchase a complete jammer, a bare amplifier module, or the antennas, cables, and power supplies. Matching components are quoted together to ensure interface compatibility.
Export documentation support
Commercial invoice, packing list, and product descriptions in English are prepared for customs clearance and tender submission. OEM labeling is available upon request.
