MMICs vs. Discrete Circuits — What Are The Trade-Offs?
 
By Ryan Foster, NuWaves

One major decision a PA module designer must make during development is the choice of architecture utilized in the amplification circuit. The two most widely used options are a monolithic microwaves integrated circuit (MMIC) or a design built around discrete components. Each approach provides advantages and particular challenges.

Spotlight On Passive Components
Introduction To A High-Efficiency, High-Density, Switched Capacitor Converter For High-Power Applications
Application Note | By Jian Li, Jeff Zhang, Ya Liu, and Marvin Macairan, Analog Devices, Inc.

The LTC7820 is a fixed ratio, high-voltage, high-power switched capacitor controller that yields small and cost-effective solutions for high-power, non-isolated intermediate bus applications with fault protection. This application note discusses the LTC7820 in detail and how it is used in these high-power applications.

The Importance Of Filters In Point-To-Point Microwave Cellular Backhaul Networks
Application Note | Anatech Electronics Inc.

To satisfy backhaul demand and maintain high data rates without holes in coverage, wireless carriers are adding large numbers of micro and pico cells to fill in the gaps in conjunction with traditional macro cells. 

Using Tantalum Hybrid Capacitors For High-Power Pulse Applications
Application Note | Evans Capacitor Company

High-power pulse applications require bulk capacitance, high currents, and fast response time for pulse forming. EVANSCAPS tantalum hybrid capacitors provide low ESR and high power density for high-current pulse power in phased array radars or laser drivers.

A Review Of GaN On SiC, High-Electron Mobility Power Transistors And MMICs
White Paper | By Raymond S. Pengelly, et al., Wolfspeed, A Cree Company

This paper summarizes the unique advantages of gallium–nitride power transistors (GaN HEMTs) compared to other power transistor technologies, with examples of where such features have been exploited.

Automatic And Fail-Safe Biasing Of GaN Transistors
Application Note | Integra Technologies, Inc.

Since GaN HEMT transistors are depletion mode devices, it is critical to supply a negative voltage to the gate before any positive voltage is applied to the drain; otherwise, the transistor will draw its maximum possible drain current from the supply.
