概要

The F1441 is a high-linearity variable gain RF amplifier with an integrated digital step attenuator (DSA) designed to operate within the 1350MHz to 2800MHz frequency range. Using a single 5V power supply, the F1441 typically provides 40dB of gain, 2.5dB of noise figure, 41dBm of OIP3, and 27dBm OP1dB at its maximum gain setting.

The F1441 is packaged in a 5 × 5 mm, 32-VFQFPN package, with an external input BOM configurable differential 50Ω or 100Ω input and single-ended 50Ω output impedances for ease of integration into the signal path.
