常问问题

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.

Q4: Is this a standard product or a custom solution?

This is primarily a customizable product platform. 频带, 功率水平, and interfaces can be tailored to your application.

Q5: What is the typical lead time?

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