GVA-81+: LTE Performance vs Output Power

LTE Base Station MMIC Amplifier

Mini-Circuits GVA-81+ High Dynamic Range MMIC Amplifier is designed specifically for applications which require high linear performance, particularly wideband, advanced digital communications systems such as LTE which require excellent ACLR suppression and low EVM.

The GVA-81+ provides typically +41.3 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 +6 dBm output.

The GVA-81+ is characterized using a high peak-to-average ratio OFDM signal used for next generation LTE within the 700MHz Downlink Band.
