Abstract:
Techniques for implementing and/or operating a radio frequency system, which includes a logic board that outputs an analog electrical signal indicative of data to be wirelessly transmitted from the radio frequency system and a remote head. The remote head includes an antenna that generates an electromagnetic wave to facilitate wirelessly transmitting the data, an antenna integrated circuit implemented using a first semiconductor manufacturing technique, in which the antenna integrated circuit amplifies the analog electrical signal to generate a first amplified analog electrical signal, and a remote front-end integrated circuit coupled between the antenna integrated circuit and the antenna. The remote front-end integrated circuit is implemented using a second semiconductor manufacturing technique different from the first semiconductor manufacturing technique and amplifies the first amplified analog electrical signal based on a target output power of the antenna to generate a second amplified analog electrical signal indicative of the data.
