よくある質問

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

• 470–520 MHz (50 MHz帯域幅)

• 630–680 MHz (50 MHz帯域幅)

Each band supports:

• 出力電力: +37 dBmの (≈5 W)

• 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 W output, or can your amplifier work directly with my modulator?
A: Our amplifier module can achieve 2 W output directly with a modulator output as low as -12.75 dBmの. No extra driver module is required.

ヒント: The amplifier input originally has a 15 dB attenuation. To match your modulator, simply reduce the input attenuation accordingly, and the amplifier will reach full power.
