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...

Both the buck circuit and the boost circuit are important circuits in hardware design, especially for intelligent ONUs and OLT devices. The VOICE function in ONU design uses the boost circuit to directly boost the voltage and supply power to external phones. The best way...

Antenna gain: The gain coefficient is a parameter that comprehensively measures the energy conversion and directional characteristics of the antenna. Its definition is: The product of directional coefficient and antenna efficiency is denoted as: D is the directional coef...
