All Application Notes

Interfacing a Differential-Output (Isolated) Amplifier to a Single-Ended Input ADC

Whether you are sensing current in an industrial 3-phase servo motor system, a battery management system for an electric vehicle, or a photo voltaic inverter, it is often necessary to...

Low-Side Current Sense Circuit Integration

Discrete implementations of current sense amplifiers are commonly used for low side current sensing applications. Low-side current sensing is when the voltage is measured across a sense resistor that is...

  • Posted Saturday, September 16, 2017
This application note gives an overview of different control mechanisms for MEMS Coriolis Vibratory Gyroscopes (CVG) and how they are implemented using the commercial off-the-shelf HF2LI Lock-in Amplifier. A MEMS...

Design and Implementation of a Bias Sequencing Circuit for the HMC463LP5 Low Noise Amplifier

The HMC463LP5 is a GaAs MMIC PHEMT Low Noise AGC Distributed Amplifier packaged in a leadless 5 x 5 mm surface mount package which operates between 2 and 20 GHz...

Use a Twist and Other Popular Wires to Reduce EMI/RFI

A twist. "The Twist." A twisted pair. Alexander Graham Bell patented twisted-pair wires in 1881. Remarkably, we still use them because they work so well. In addition, today by harnessing...

Digital RF Power Control for Power Amplifier Protection in Wireless Base-Stations

In a wireless base-station (BS), when the output power of an RF power amplifier (PA) exceeds predefined limits, the antenna and other sensitive electronic components can be permanently damaged. This...

Short-to-Battery Protection Strategies for Class-D Amplifiers

With class-D amplifiers, short-circuit faults in the output H-bridge result in dangerous current paths. This type of fault occurs when either the positive or negative outputs (OUTP or OUTN, respectively)...

Class D Audio Amplifier Using PIC24FV16KM202

Class D amplifiers have become a popular audio amplifier topology due to their high efficiency and subsequent low cost. The high current output stage is implemented using binary switches, resulting...

Linearizing Microwave Transmission Power Amplifiers Using the SC1894

This document is an introduction to linearizing a microwave transmission-system PA using Maxim's SC1894 RF PA Linearizer (RFPAL) from 4GHz to 80GHz. It includes basic system design considerations to implement...

Optimizing your Power Amplifier for Predistortion with RF PA Linearizer

This document provides guidelines for designing a power amplifier to achieve optimum performance with Maxim's radio frequency (RF) power amplifier (PA) linearizer (RFPAL) or other types of predistortion. Using RFPAL...
