часто задаються

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 смуга пропускання МГц) is not feasible due to linearity and gain-flatness limitations for COFDM. проте, we can offer customized solutions for narrower bands:

• 470–520 MHz (50 смуга пропускання МГц)

• 630–680 MHz (50 смуга пропускання МГц)

Each band supports:

• Вихідна потужність: +37 дБм (≈5 W)

• посилення: ~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 Вт вихід, or can your amplifier work directly with my modulator?
A: Our amplifier module can achieve 2 Вт вихід directly with a modulator output as low as -12.75 дБм. No extra driver module is required.

Підказка: 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.
