Preguntas más frecuentes

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

• 470–520 MHz (50 ancho de banda MHz)

• 630–680 MHz (50 ancho de banda MHz)

Each band supports:

• Potencia de salida: +37 dBm (≈5 W)

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

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