Wireless communication standard continues to evolve in order to fulfill the demand for high data rate operation. This leads to the exertion on the design of radio frequency power amplifier (RFPA) which consumes high DC power in order to support linear transmission of high data rate signal. Hence, operating the PA with low DC power consumption without trading-off the linearity is vital in order to achieve the goal of achieving fully integrated system-on-chip (SoC) solution for 4G and 5G transceivers. In this paper, the evolution of CMOS PA toward achieving a fully integrated transceiver solution is discussed through the review of multifarious CMOS PA design. This is categorized into the review of efficiency enhancement designs followed by linearity enhancement designs of the CMOS PA.

In this paper, the development of three-dimensional (3-D) millimeter-wave functions in multilayer low temperature cofired ceramic (LTCC) and liquid crystal polymer (LCP) technologies is presented for millimeter-wave compact and easy-to-design passive solutions for high data rate wireless systems. Both ceramic and organic technologies are candidates for the 3-D integration of system-on-package (SOP) miniaturized RF/microwave/millimeter-wave systems. LTCC has been widely used as a packaging material because of its process maturity/stability and its relatively high dielectric constant that enables a significant reduction in the module/function dimensions. As an alternative, LCP is an organic material that offers a unique combination of electrical, chemical, and mechanical properties, enabling high-frequency designs due to its ability to act as both the substrate and the package for flexible and conformal multilayer functions. A LTCC patch resonator filter that uses vertical coupling overlap and transverse cuts as design parameters has been designed to achieve a high level of miniaturization and a great compromise between compactness and power handling. Excellent agreement between the simulation and the measurement has been verified for two operating frequency bands (58–60GHz/38–40GHz) of RF communications and sensors for applications such as wireless broadband internet or inter-satellite communications. A band pass filter has been fabricated on LCP substrate, offering a very simple, low loss flexible and low lost filtering solution for wideband millimeter waves applications such as 60 GHz WLAN short-range gigabit wireless systems. The design exploits the ripple near the cut off frequency of Tchebysheff low pass filter to create a band pass response and it exhibits the insertion loss as low as 1.5 dB at the center frequency of 60GHz and 3-dB bandwidth of 16.7% (∼10 GHz).
