NXP Semiconductors RAPIDRF-26E39 RapidRF Front-End Design
NXP Semiconductors RAPIDRF-26E39 RapidRF Front-End Design provides a reference design for 5G infrastructure, based on the AFSC5G26E39 Airfast® Power Amplifier Module. The AFSC5G26E39 is a fully integrated Doherty power amplifier module with a 2496MHz to 2690MHz frequency range. The device is optimized for applications such as massive MIMO systems, outdoor small cells, and low-power remote radio heads.
The NXP Semiconductors RapidRF Front-End Designs integrate an RF power amplifier, Rx LNAs, a T/R switch, a circulator, and a bias controller in a compact footprint. They incorporate a coupler for DPD feedback and are to be used with digital pre-distortion.
The RapidRF Reference Boards are ideal for 5G radio units requiring 2.5W to 5.0W (34dBm to 37dBm) average transmit power at the antenna. Versions for different bands use a common PCB layout, simplifying both design and manufacturing for faster time-to-market.
