5 to 210 MHz Push-Pull CATV Return Path Amplifier IC

The DMA2320 is a general purpose, low-cost, high-linearity push-pull (PP) RF amplifier IC. Employing two complimentary amplifier die manufactured on an advanced GaAs process, this linear CATV amplifier is ideal for high data rate broadband systems. Its gain flatness of better than ±0.5 dB from 5 MHz to 210 MHz combined with an OIP2 of >+70 dBm and OIP3 of >+44 dBm at 100 MHz, make this part ideal for cable TV and infrastructure IF applications. The part is available in a small outline, low profile SMT package.
