5G Ka-Band Power Amplifier Module

The DMA2818 is a high gain, high RF output power amplifier module (PAM) enabling 5G Ka-Band uplink (UL) and downlink (DL) TDD and full duplex (FD) transmitters, including BTS, HetNet, and user equipment (UE). Employing amplifier die manufactured on an advanced InP process, this high efficiency linear 50 Ω input/output (I/O) amplifier is ideal for low power dissipation and low distortion applications. Designed for use as an easily cascadable gain block, its gain flatness of better than ±0.5 dB within the LMDS A1 band make this part ideal for highly integrated MIMO and MA-MIMO applications. The part is available in a small outline, low profile SMT package.
