Підсилювач радіочастот FDD

Огляд

The Підсилювач радіочастот FDD is a professional-grade RF amplification solution designed for Дуплекс з частотним поділом (FDD) системи бездротового зв'язку. It supports simultaneous transmission and reception on separate frequency bands, delivering high output power on the TX path and low-noise, high-linearity amplification on the RX path.

This amplifier is engineered for custom frequency requirements, making it ideal for applications where standard off-the-shelf RF amplifiers cannot meet system-level performance, isolation, or integration demands. It is widely used in COFDM data links, Системи зв'язку БПЛА, наземні станції, and other professional wireless platforms.
