پرسش و پاسخ

س: Can you provide a 470–680 MHz broadband UHF power amplifier for DVB-T2/COFDM with +37 dBm output and 50 افزایش دسی بل?
آ: A single amplifier covering the full 470–680 MHz band (210 پهنای باند مگاهرتز) is not feasible due to linearity and gain-flatness limitations for COFDM. However, we can offer customized solutions for narrower bands:

• 470–520 MHz (50 پهنای باند مگاهرتز)

• 630–680 MHz (50 پهنای باند مگاهرتز)

Each band supports:

• توان خروجی: +37 DBM به (≈5 W)

• به دست آوردن: ~50 dB

• High linearity for DVB-T/T2 COFDM signals

If you require a specific sub-band, we can provide a tailored specification.

س: My modulator output is low. Do I need a driver to reach 2 خروجی W, or can your amplifier work directly with my modulator?
آ: Our amplifier module can achieve 2 خروجی W directly with a modulator output as low as -12.75 DBM به. No extra driver module is required.

نکته: The amplifier input originally has a 15 تضعیف دسی بل. To match your modulator, simply reduce the input attenuation accordingly, and the amplifier will reach full power.
