LTE Base Station MSiP Amplifier

Mini-Circuits YSF-322+ high dynamic range MSiP amplifier is designed specifically for applications which require high linear performance, advanced digital communications systems such as LTE which require excellent ACLR suppression and low EVM.

The YSF-322+ provides typically +35 dBm OIP3 which translates to high linear performance in multi-carrier and complex signal environments such as LTE supporting ACLR_1 measurements of better than -60 dBc at +4 dBm output.

The YSF-322+ is characterized using a high peak-toaverage ratio OFDM signal used for next generation LTE within the 1900MHz downlink band.
