التعليمات

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

• 470–520 MHz (50 عرض النطاق الترددي ميغاهيرتز)

• 630–680 MHz (50 عرض النطاق الترددي ميغاهيرتز)

Each band supports:

• طاقة الإخراج: +37 ديسيبل (≈5 W)

• يكسب: ~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 إخراج دبليو, or can your amplifier work directly with my modulator?
أ: Our amplifier module can achieve 2 إخراج دبليو directly with a modulator output as low as -12.75 ديسيبل. No extra driver module is required.

نصيحة: 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.
