1. Integrated Filter–Amplifiers: A Comprehensive Review.

Author

Gao, Yang, Shang, Xiaobang, Li, Lei, Guo, Cheng, and Wang, Yi

Abstract

Amplifiers and filters are essential components in microwave systems. An amplifier is used to increase the signal strength, and it is usually cascaded by filters for frequency selection or harmonic rejection –. Their functionalities require a precise design of the individual parts as well as the way in which they are connected. The common approach is to make individual components with a system impedance that is usually ${50}\Omega{.}$ A generic example of the filters and amplifier in a generalized receiver is shown in.

Abstract

We report on the super-lattice castellated field-effect transistor (SLCFET) device architecture whose unique geometry enables new scaling and optimization strategies for RF power and performance. Measured transistor values show excellent potential for both power and low-noise amplification applications. With ${I}_{\text {DS}} > \text {1.8}$ A/mm, ${f}_{T}=\text {47}$ GHz, and ${f}_{\text {max}}=124$ GHz, we are able to demonstrate ${P}_{out} >6$ W/mm, PAE >45%, and OIP3/PDC = 6 dB at 30 GHz.
