NXP Introduces an Innovative MMIC Family

Xavier Moronval, NXP Semiconductors

As a leader in RF Power products for base-station applications, NXP is expanding its portfolio with an innovative LDMOS MMIC product family. For the first time, the MMICs were designed using a modular approach. It consists in developing independent MMIC building blocks at different power levels, and then combined them together to make the final products. The interest of this approach lies in the full flexibility on the combination of the blocks to allow symmetric or (as an industry first) asymmetric MMICs in a two-pipe package. Using asymmetric MMICs is very powerful to boost the efficiency of the complete base station power amplifier: they can be used in class AB operation to drive an asymmetric Doherty final, or they can be combined in a Doherty configuration to be used as a driver in macro base stations or as a final for small cells. During the proposed presentation, the modular approach will be described in details and the performance of a very wideband 20W MMIC (34% fractional bandwidth at 2GHz central frequency) will be presented. Finally, as a practical implementation, the performance of a 20W/40W Asymmetric MMIC Doherty will be shown and compared to a conventional 30W/30W symmetric MMIC Doherty.
