LTE Base Station MMIC Amplifier

Mini-Circuits PHA-1+ ultra high dynamic range MMIC amplifier is designed specifically for applications which require extremely linear performance, particularly wideband, advanced digital communications systems such as LTE which require excellent ACLR suppression and low EVM.

The E-PHEMT based PHA-1+ provides typically +42 dBm OIP3 which translates to extremely linear performance in multi-carrier and complex signal environments such as LTE supporting ACLR_1 measurements of better than -60 dBc at +10 dBm output and -26 dBc at +20dBm (near the 1 dB compression point).

The PHA-1+ is characterized using a high peak-toaverage ratio OFDM signal used for next generation LTE within the AWS-1 downlink band.
