Description
The F4482 is a 1300MHz to 2800MHz 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 485mA of I
CC
, the F4482
provides four independent transmit paths, each with 27.5dB typical
maximum gain, +16.5dBm 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
