Embodiment Construction

[0045] One or more specific embodiments of the present disclosure are described below. These described embodiments are merely examples of the presently disclosed technology. Additionally, while an attempt is made to provide a brief description of these embodiments, not all features of an actual implementation may be described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, decisions specific to many implementations must be made to achieve the developer's specific goals, such as conformance may vary from one implementation to Another implementation-specific system-related and business-related constraint. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

Abstract

Techniques for implementing and / or operating a radio frequency system 12, which includes a logic board that outputs an analog electrical signal indicative of data to be wirelessly transmitted from the radio frequency system 12 and a remote head 78. The remote head 78 includes an antenna 34 that generates an electromagnetic wave to facilitate wirelessly transmitting the data, an antenna integrated circuit 96 implemented using a first semiconductor manufacturing technique, in which the antenna integrated circuit 96 amplifies the analog electrical signal to generate a first amplified analog electrical signal, and a remote front-end integrated circuit 98 coupled between the antenna integrated circuit 96 and the antenna 34. The remote front-end integrated circuit 98 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 34 to generate a second amplified analog electrical signal indicative of the data.
