Overview
Description
The F1440 is a high-linearity variable gain RF amplifier with an integrated digital step attenuator (DSA) designed to operate within the 500MHz to 1000MHz frequency range. Using a single 5V power supply, the F1440 typically provides 42.5dB of gain, 3.2dB of noise figure, 41.5dBm of OIP3, and 30dBm OP1dB at its maximum gain setting.
