The F1441 is a 高-linearity variable 获得 RF amplifier with an integrated digital 步 attenuator (DSA) designed to operate within the 1350MHz to 2800MHz 频率范围. Using a single 5V power supply, the F1441 typically provides 40dB of 获得, 2.5dB of noise figure, 41dBm of OIP3, and 27dBm OP1dB at its maximum 获得 setting.
The F1441 is 包裹d in a 5mm x 5mm, 32-VFQFPN 包裹, with an external input BOM configurable differential 50? or 100? input and single-ended 50? 输出阻抗s for ease of integration into the signal path.
- FDD or TDD 5G sub-6GHz wireless 基础设施
- Repeaters and DAS
- General-purpose RF
