AD9371 and ADRV9009 RF Port Hardware Design Guidelines

Transmitter Port DC Feed The transmitter port of this series of transceivers is a push-pull differential RF driver. Like the usual RF amplifier, it needs DC feed to provide power, resulting in Two ways of feeding (that is, DC bias), one is to use an external RF choke for feeding, and

It is not difficult at all to understand these indicators of switching power supply design!

1. Input voltageChina is generally 220V. Due to the instability of the grid voltage, a wide voltage input is often required, so it is designed to work normally at 90-270V. Usually the US electricity range is 110-130V, and Japan’s electricity range is 100V.2. The ripple of the output voltageSince th

Brief analysis of BMS sampling board design scheme of lithium iron phosphate battery bms scheme

In the domestic rear-drive version of MODEL 3, the CATL lithium iron phosphate battery is used. The BMS acquisition board on the battery pack is of a different design than before. Let’s learn together today. Ningde The ferroelectric core module version of MODEL 3 has 4 acquisition boards on a ba

How to use IS802 as an isolated power supply?

It can be seen from the data sheet that IS802 is a power supply with a push pull architecture, with a total of 6 pins. After reading the schematic diagram, the only thing that is not clear is the Ext clock, so let's take a look at the Ext clock. what's going on.The pin function in the manual

Shorten comparative analysis time with SpeedFit design simulation software

In the process of power supply design and debugging, when we encounter problems, we should put our thoughts into the inside of the power supply, and if we are in the power control part, what should we do if we encounter such problems? solve. That is to consider the problem from the perspective of th
