    Difference between Main Antenna and Rx-diversity antenna

    I am using Quectel SC200 in my design .Below is the description of it's antenna interface. SC200E-CE/-EM/-NA and SC206E-EM/-NA provide four antenna interfaces for the main, Rx-diversity,Wi-Fi/Bluetooth, and GNSS antennas respectively. I understood all the other antenna specifications except...

    How to calculate signal rise time from frequency

    Dear Team, May I know how to calculate a signals rise time from it's frequency. I found this article for the same. The formula given is Tr = 1/f*π. May I know is this applicable for PWM also.

    Will decoupling capacitors cause radiated emission

    Thank you. The decoupling path here I mean is Decoupling capacitor for Microcontroller VDD(Power supply rail) The controller is placed in TOP and the Decoupling capacitors for this controllers VDD rail is present on bottom layer L6

    Will decoupling capacitors cause radiated emission

    I am debugging a 6 layer board for RE issue and the stackup is (S G G P+G G S).This is a 6 layer board. The microcontroller is present in TOP(L1) layer and decoupling capacitor is placed in bottom layer(L6). I was told that "When you decouple through vias, you are always going to get the IO...

    DS90UB928Q-Q1: Horizontal Sync and Vertical Sync pins of DS90UB928Q-Q1

    I am using DS90UB928Q-Q1 in y design.The output of this IC will be connected to LCD. The LCD has dedicated Horizontal Sync and Vertical Sync pins. In the datasheet of DS90UB928Q-Q1 I can see that ,there is no dedicated pins for Horizontal Sync and Vertical Sync. But in the datasheet I can see...

    Power over coax schematic review

    May I know can I connect multiple ferrite beads in series to improve the impedance. As per my self study goal of the PoC filter is to make the impedance of the PoC delivery network much higher than the impedance of the 50-ohm transmission line so that the high speed signal edges don't "see"...
