常问问题

Q: Can you provide a 470–680 MHz broadband UHF power amplifier for DVB-T2/COFDM with +37 dBm output and 50 分贝增益?
一个: A single amplifier covering the full 470–680 MHz band (210 MHz带宽) is not feasible due to linearity and gain-flatness limitations for COFDM. 然而, we can offer customized solutions for narrower bands:

• 470–520 MHz (50 MHz带宽)

• 630–680 MHz (50 MHz带宽)

Each band supports:

• 输出功率: +37 分贝 (≈5 W)

• 获得: ~50 dB

• High linearity for DVB-T/T2 COFDM signals

If you require a specific sub-band, we can provide a tailored specification.

Q: My modulator output is low. Do I need a driver to reach 2 输出功率, or can your amplifier work directly with my modulator?
一个: Our amplifier module can achieve 2 输出功率 directly with a modulator output as low as -12.75 分贝. No extra driver module is required.

提示: The amplifier input originally has a 15 分贝衰减. To match your modulator, simply reduce the input attenuation accordingly, and the amplifier will reach full power.
