Advantages

Low Insertion Loss <1 dB
The switch employs an optimized RF matching network and low-loss semiconductor technology, resulting in insertion loss of less than 1 dB, effectively reducing signal attenuation.

Fast Switching Speed
The internal drive structure utilizes a high-speed switching crystal structure design, enabling switching action times faster than 150 ns.

Ultra-Wide Operating Temperature Range
The device employs a high-reliability package (eMSOP8 / SOT23-6) and temperature compensation technology, ensuring stable performance under extremely cold or high temperature conditions.

Packaging and Transportation

Anti-static tape and reel or tray packaging is used to ensure that components are protected from electrostatic damage and mechanical shock during transportation.

The outer carton is a thickened corrugated cardboard box with a moisture-proof bag, suitable for sea, air, and express delivery.
