描述 Description

The QPL9547 is a high-linearity, ultra-low noise amplifier in a small 2 x 2 mm surface-mount package. At 1.9 GHz, the amplifier typically provides 19.5 dB gain, +39 dBm OIP3 at a 65 mA bias setting, and 0.3 dB noise figure. The LNA can be biased from a single positive supply ranging from 3.3 to 5 volts. The device is housed in a green/RoHS-compliant industry-standard 2x2 mm package.The QPL9547 is bias adjustable and requires minimal external components to operate. It also has a power down control capability integrated into the die for TDD applications.
