Challenges and Requirements of Multimode Multiband Power Amplifiers for Mobile Applications

From Skyworks Solutions, Inc.

developed in recent years for next generation mobile
handsets and tablets applications. Designers face new and
greater challenges due to more stringent requirements in
functionality, performance, size and cost. This paper will discuss
the motivations that drive MMMB PA development and the
requirements, challenges and considerations relevant to power
amplifier design.

IC Phase-locked Loops (PLLs)
IC phase-locked loops (PLL) are closed-loop frequency controls that are based on the phase difference between the input signal and the output signal of a controlled oscillator.
Bluetooth® Chips
Bluetooth® chips are board level components which broadcast in the 2.4 GHz industrial, scientific, and medical (ISM) radio band.
WiFi and WiMAX Wireless Chips
WiFi wireless chips and WiMAX wireless chips are used in fixed broadband wireless access networks that use point-to-multipoint architecture.
RF and Wireless Chips
RF and wireless chips are integrated circuits (IC) that are designed specifically for radio frequency (RF), microwave, and other wireless communications or data transmission applications.
Network and Communication Chips
Network and communication chips are semiconductor integrated circuits (IC) used in telecommunication devices and systems.
