RFMW, Ltd. announces design and sales support for an ultra low-noise amplifier with flat gain. With an operational bandwidth of 600 to 4200 MHz, the Qorvo QPL9057 provides a gain flatness of 2.4 dB (peak-to-peak) over a wide bandwidth from 1.5 to 3.8 GHz. At 3.5 GHz, the amplifier typically provides 22.8 dB gain, +32 dBm OIP3 at a 50 mA bias setting, and 0.54 dB noise figure. The LNA can be biased from a single positive supply ranging from 3.3 to 5 volts. Bias adjustable for linearity optimization, the QPL9057 supports Macro BTS, TDD/FDD systems, Repeaters and DAS.
