Unused PolyPhaser AL-LSXM-ME is a broadband RF surge protector designed for applications where low loss, strong surge handling, and consistent RF performance are required. This unit utilizes a filter-based suppression design with DC block, making it ideal for systems requiring DC isolation while maintaining RF continuity.

Operating across a 2 GHz to 6 GHz frequency range, the AL-LSXM-ME delivers excellent electrical performance, including low insertion loss (typically 0.1–0.2 dB) and VSWR in the range of approximately 1.2:1 to 1.3:1, ensuring minimal impact to system efficiency when installed inline.

The unit is built on a 50-ohm impedance platform and supports low power RF applications (approximately 10 watts CW), making it well suited for receive paths, low-power transmit systems, and sensitive RF front-end protection.

For surge protection, it is rated at approximately 10 kA (8/20 µs waveform), providing effective defense against lightning-induced transients and electrical surges. The internal filter design also supports excellent passive intermodulation (PIM) performance, typically in the -155 to -167 dBc range, making it appropriate for modern multi-carrier and high-density RF environments.

The AL-LSXM-ME features a compact bulkhead-mount design with Type-N female and male connectors for straightforward inline installation. Its environmentally sealed construction (IP67 rated) allows for reliable outdoor deployment in demanding conditions.

Key features include:

• DC Block design (no DC pass)
• Wideband operation: 2–6 GHz
• Low insertion loss and controlled VSWR
• High surge handling capability (10 kA)
• Low PIM performance for critical RF systems
• Rugged, weather-resistant housing

This unit is well suited for cellular, DAS, microwave, public safety, and RF systems where maintaining signal integrity while providing robust surge protection is essential.
