The F4481 is a 400MHz to 1100MHz quad path TX Digital Variable 获得 Amplifier (DVGA) outfitted with 100? differential inputs and 50? single-ended outputs. The device is part of a complete family of VGAs targeting Frequency Division Duplex (FDD) or Time Division Duplex (TDD) 应用s within the 400MHz to 4200MHz 频率范围. Using a single 3.3V power supply and only 520mA of ICC, the F4481 provides four independent transmit paths, each with 28dB typical maximum 获得, +35dBm OIP3, +17dBm output P1dB, and 5.7dB NF. Each channel includes a Glitch-Free™ digital 步 attenuator that reduces 获得 by up to 31.5dB in precise 0.5dB 步s.
The F4481 is 包裹d in an 8mm × 8mm 56-LGA, with matched 100? differential input and 50? single-ended 输出阻抗s for ease of integration into the signal path.
