Technical Note LTE Performance vs. Output Power Model: PMA-545+ AN-60-054 LTE Base Station MMIC Amplifier Mini-Circuits PMA-545+ High Dynamic Range and Super Low Noise 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. Figure 1 PMA‐545+ Test Board The E-PHEMT based PMA-545+ provides typically +36 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.
