With so much attention on IBOC, it is appropriate to step back and review the basic principles of RF amplifiers. The radio transmitter is a collection of stages. Each stage modifies the signal in some ...
This article presents the challenges in designing RF power amplifier efficiency. It briefly describes the use of different amplifiers and techniques to create an effective result. This article ...
Evaluating S-parameters and other CW stimulus responses is essential for characterising rf amplifiers. An rf vector network analyser (VNA) plays a critical role for this purpose, and proper ...
Radio frequency (RF) enabled Wireless Power Transfer (WPT) has been around for a long time, however recent development of low power electronics and advanced waveform optimization techniques [1, 2] ...
Qorvo (Nasdaq: QRVO) introduced the QPA9510, a compact RF power amplifier that delivers wideband coverage from 100 to 1000MHz ...
Despite recent improvements in the performance of RF LDMOS field-effect transistors (FETs), temperature drift and aging continue to affect the efficiency and linearization of power amplifiers using ...
Qorvo's new compact, high-efficiency RF power amplifier covering 100 to 1,000 MHz facilitates design and reduces parts in sub ...
An RF power amplifier is a device designed to convert a low power radio frequency signal into a higher power radio frequency signal. Moreover, based on several parameters RF power amplifiers are ...
Typically, amateur radio operators use the minimum power needed to accomplish a contact. That’s just part of being a good spectrum citizen, and well-earned bragging rights go to those who make ...
Guerrilla RF’s GRF5509 high-performance power amplifier paired with Impinj’s advanced RAIN RFID reader chips to enable increased read range and improved readability of RAIN RFID tags GREENSBORO, N.C., ...
GREENSBORO, N.C.--(BUSINESS WIRE)--Guerrilla RF, Inc. (OTCQX: GUER) today announced that its high-efficiency GRF5509 4-watt power amplifier was selected by Impinj (NASDAQ: PI) for use in their ...
