Product Description
ATD412.5M452.5M02N is a high-performance cavity duplexer designed specifically for wireless communication applications from 440MHz to 470MHz. Its low insertion loss design (typical value ≤1.0dB, ≤1.75dB over temperature range) and high return loss (≥20dB at room temperature, ≥15dB over full temperature range) provide high-quality signal transmission and efficient frequency isolation.
The product also has excellent signal suppression performance, with a suppression value of ≥85dB at F0±10MHz, effectively reducing signal interference and ensuring signal quality. It also supports power input up to 100W, suitable for various high-demand wireless communication environments.
Its dimensions are 422mm x 162mm x 70mm, and it adopts a white coating design, which is not only durable but also has good corrosion resistance. The product is equipped with an N-Female interface, which is easy to install and suitable for various application scenarios.
Customization service: We can provide customization services for specific frequency ranges, interface types and other parameters according to customer needs to meet different application requirements.
Quality assurance: This product has a three-year warranty to ensure that customers can use it without worries.
