How to determine the three poles first? The identification of the three pins on the MOS transistor symbol should focus on key points: G-pole, needless to say, is relatively easy to recognize. The S-pole, whether it is a P-channel or an N-channel, intersects two lines. D-...

The through-hole itself has parasitic capacitance to the ground. If the diameter of the isolation hole on the floor layer of the through-hole is known to be D2, the diameter of the through-hole pad is D1, the thickness of the PCB board is T, and the dielectric constant o...

Composition of BOSA: The light emitting part is called TOSA; The light receiving part is called ROSA; When two come together, they are called BOSA. Electric to Optical TOSA: LD (Laser Diode) semiconductor laser, used to convert electrical signals into optical signals for...

Firstly, let's take a look at the general design diagram of WiFi RF circuits: (The WiFi design diagram is generally divided into these modules, with the blue area of RTL8192FR integrated in the MCU) Differenti...

An important standard indicator of Barron is its balance, which is the degree to which two balanced outputs (one is 180 ° inverted output and the other is non inverted output) are close to the ideal state of 'equal power level, 180 ° phase difference'. The phase angle di...

Balun is a three port device, or a broadband transmission line transformer that connects balanced and unbalanced transmission line circuits by converting matching inputs into differential outputs. The function of Barron is to enable the system to have different impedance...
