Systems4Silicon's power amplifier linearisation technology demonstrates >70 dB ACLR for the latest APCO P25 Phase 2 modulation (H-DQPSK) at >100 Watts antenna power. This milestone represents an ACLR improvement of around 35 dB relative to the unlinearised amplifier and is the first known application of Digital PreDistortion (DPD) that enables compliance with the APCO P25 standard.
