02.16.23 -- Bias And RF Sequencing For GaN And LDMOS RF Power Devices

PLLs are used to generate RF and IF signals from less than 1 MHz to 10s of GHz and higher. Application requirements vary widely, and PLL design and optimization involves trading off parameters such as power consumption, phase noise, frequency tuning range, frequency resolution, and lock time.

Qorvo's recently developed Ultra-Wideband For Dummies book is a quick guide to understanding the UWB basics along with the latest trends and applications.

Microstrip technology, first released in 1952, has been adopted for a wider range of applications, especially at mmWave frequencies. 

JFW has introduced a number of new products to support testing the full range of frequencies allotted by Wi-Fi 6E.

In the world of wireless communication, the airwaves are continually getting more and more crowded. More stringent demands often come with a higher price tag due to difficulties in production. Tighter specs mean tighter dimensional requirements, more precision while tuning, and no room for error. All of these factors drive up cost and time. If we can save time by focusing on our tuning methods, we can lower costs and drive down lead times.

The R&S LCX LCR meter is ideal for measuring frequency, signal level, and DC bias. The R&S^® LCX sweep tool is an application program for conveniently performing such sweeps and displaying the results on charts.

If you're producing integrated circuit (IC) products for electromagnetic environments, you must test and pass all the regulatory electromagnetic interference (EMI) and safety requirements. Electromagnetic compatibility (EMC) testing is performed to ensure these components can be used in the intended environment without failing, degrading, or causing other equipment to fail.

GaN HEMT (high-electron-mobility transistor) and LDMOS MOSFET (metal-oxide semiconductor field-effect transistor) are voltage-controlled field-effect transistors requiring specific bias sequencing to ensure safe operation.
