Hỏi đáp

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

• 470–520 MHz (50 băng thông MHz)

• 630–680 MHz (50 băng thông MHz)

Each band supports:

• Công suất đầu ra: +37 dBm (≈5 W)

• Nhận được: ~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?
Một: Our amplifier module can achieve 2 W output directly with a modulator output as low as -12.75 dBm. No extra driver module is required.

Mẹo: 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.
