Description
The F4481 is a 400MHz to 1100MHz Quad Path Tx DVGA with
matched 100Ω differential input and 50Ω single-ended output
impedances for ease of integration into the signal path.
Using a single 3.3V power supply and only 520mA of I
CC
, the F4481
provides four independent transmit paths, each with 28dB typical
maximum gain, +17dBm output P1dB. Each channel includes a
glitch-free digital step attenuator that reduces gain by up to 31.5dB
in precise 0.5dB steps.
Packaged in an 8 × 8 mm, 56-LGA package, this device is part of
a complete family of VGAs targeting FDD and TDD applications
within the 400MHz to 4200MHz frequency range.
Typical Applications
4G and 5G multi-mode, multi-carrier transmitters
LTE and UMTS/WCDMA base stations
Active antenna systems
Digital radio
