Anti Jamming Antenna | Anti Jamming Gnss Antenna

Overview

JM008 is an ultra-compact anti-jamming integrated antenna that combines an anti-jamming module, a four-element antenna array, and a receiver into one unit. It is capable of suppressing various types of broadband and narrowband interference, which supports GPS L1, BDS B1. With its outstanding interference suppression performance, it is widely suitable for integrated applications in complex electromagnetic environments such as marine vessels, unmanned aerial systems.

Key Features

Chip-Based and Highly Integrated Design

JM008 adopts a highly integrated dual-chip architecture consisting of a 4-channel anti-jamming RF chip and an anti-jamming baseband processing chip. This design significantly improves overall system reliability, while also enabling a highly integrated all-in-one solution.

Integrated Multi-Element Anti-Jamming Antenna

JM008 delivers outstanding anti-jamming performance for demanding operational environments. It supports GPS L1 and BDS B1 signal reception, and effectively suppresses a wide range of broadband and narrowband jamming signals, including harmonic, sweep, pulse, FM, and PM interference.

Superior Anti-Jamming Capabilities

JM008 can effectively suppress interference signals from three signal sources. For single interference source, the suppression capability is no less than 90dB; for three interference sources, the suppression capability is no less than 80dB.

Compact, Low-Power and Lightweight Design

JM008 features a highly integrated dual-chip architecture and all-in-one design that significantly reduces overall size, power consumption, and weight. It features a compact form factor of just 65*65*22 mm, total power consumption of less than 9 W, and a weight of under 130 g.
