FDD射頻放大器

FDD射頻放大器

Overview

The FDD射頻放大器 is a professional-grade RF amplification solution designed for 頻分雙工 (頻分雙工) wireless communication systems. 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, 隔離, or integration demands. It is widely used in COFDM data links, UAV communication systems, 地面站, and other professional wireless platforms.

常問問題

Q1: Can this FDD radio frequency amplifier support very wide TX frequency ranges?

是. 然而, extremely wide TX ranges (such as 300–2500 MHz) are typically implemented using segmented frequency designs to ensure stable gain, 效率, and linearity.

Q2: Is the RX path protected from TX leakage?

是. The design includes optimized TX/RX isolation and supports external or integrated duplexers to protect the RX LNA from high TX power.

Q3: Can the amplifier work with COFDM or DVB-T/T2 signals?

是. The amplifier is designed to support wideband digital modulation schemes with good linearity and spectral performance.

第四季: Is this a standard product or a custom solution?

This is primarily a customizable product platform. 頻段, 功率等級, and interfaces can be tailored to your application.

Q5: What is the typical lead time?

Typical sample lead time is 4–8 週, depending on frequency range and performance requirements.
