F4482

DIFF-In / SE-Out Quad Path TX DVGA - 1300MHz to 2800MHz

The F4482 is a 1300MHz to 2800MHz Quad Path TX DVGA outfitted with 100Ω differential inputs and 50Ω single-ended outputs. The device is part of a complete family of VGAs targeting FDD and TDD applications within the 400MHz to 4200MHz frequency range.
Using a single 3.3V power supply and only 485mA of ICC, the F4482 provides four independent transmit paths, each with 27.5dB typical maximum gain, +36.8dBm OIP3, +16.5dBm output P1dB, and 5.7dB NF. Each channel includes a glitch-free digital step attenuator that reduces gain by up to 31.5dB in precise 0.5dB steps.
 
The F4482 is packaged in an 8 × 8 mm 56-LGA, with matched 100Ω differential input and 50Ω single-ended output impedances for ease of integration into the signal path.
