FAQ

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

• 470–520 MHz (50 Bande passante MHz)

• 630–680 MHz (50 Bande passante MHz)

Each band supports:

• Puissance de sortie: +37 dBm (≈5 W)

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

Conseil: 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.
