QPL9547 0.1 -6 GHz Ultra Low-Noise LNA Product Overview 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 8 Pin 2X2 mm DFN Package be biased from a single positive supply ranging from 3.3 to 5 volts. The device is housed in a green/RoHS-compliant Key Features industry-standard 2x2 mm package. 0.1-6 GHz Operational Bandwidth The QPL9547 is bias adjustable and requires minimal Ultra low noise figure, 0.3 dB NF 1.9 GHz external components to operate. It also has a power down 39 dBm OIP3 control capability integrated into the die for TDD 19.5 dB small signal gain applications. Bias adjustable for linearity optimization Unconditionally stable Shut-down mode pin with 1.8V logic Maintains OFF state with high Pin drive Functional Block Diagram Applications 5G m-MIMO Repeaters / DAS Mobile Infrastructure LTE / WCDMA / CDMA / GSM General Purpose Wireless TDD or FDD systems Ordering Information Part No. Description Top View QPL9547TR7 2500 pieces on a 7 reel QPL9547EVB-01 0.6-4.2 GHz Evaluation Board Data Sheet, Rev.
