WIFI Design Summary – Barron

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) Differential signal processing: Generally, WiFi RF signals are processed using differen...

Balun circuit – balance degree

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 difference betwe... Read More

Baron circuit

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 impedances or be compatible with di... Read More

boost circuit

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 to understand the boost c... Read More

Characteristics of ONU antenna

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 coefficient and is the antenna... Read More

Basic knowledge of ONU product antennas

Antennas convert electrical signals transmitted by devices into electromagnetic waves for transmission. Generally, antennas have the function of transmitting and receiving, but in special cases, they only perform the function of receiving. (such as broadcast antenna) The definition of an antenna ...
