The RapidRF front-end reference designs from NXP Semiconductors are now available from distributor RFMW with full design support.

Accelerating design time and prototyping for massive MIMO radio units, or small cell output devices or even as drivers for high-power macro base stations, these reference boards incorporate a T/R switch, circulator, Rx LNA, Rx linear amplifier, Tx path pre-drivers and an asymmetrical Doherty output.

Also included are the TDD I2C logic controls for a complete 5G, TDD radio system RF front-end solution.

Ideal for transmitters requiring 2.5 to 5 watts average at the antenna with approximately 8.5 dB PAR LTE/NR signals, RapidRF reference boards can be linearised for up to 200 MHz instantaneous bandwidth while meeting regulatory emissions requirements when used in conjunction with digital pre-distortion.
