To maintain a competitive edge, original equipment manufacturers (OEMs) are pushing for functional components that are smaller and more cost-effective, all while maintaining utmost quality. One such critical component is the radio frequency front end. In this paper, we discuss the challenges facing radio frequency (RF) front end manufacturers and integration efforts in the front end industry, and we provide some technological and application-based insights on the next generation of integrated modules called multimode multiband power amplifiers (MMPAs).
There are some common themes that span across electronic warfare, radar, and communications that are going to underpin future system design. These include the ability to operate across wider bandwidths and at higher frequencies while generating suitable output power in the transmit chain or offering sufficient low-noise capabilities in the receiver. Practical requirements related to portability, flexibility, and modularity also dictate design, and other considerations include cost and reliability.
The expansion of 2G/3G wireless networks across the world has made it far easier for machine-to-machine (M2M) communication to take place and has lessened the amount of power and time necessary for information to be communicated between machines. But, due to the additional complexity in M2M applications, potential problems can occur. In order to avoid unpredicted costs, it is imperative to test and validate key traffic and signaling behavior in a test environment.
