'> What are baseband chips, aps, and RF chips, and what do they do in a phone?
1, the RF chip generally refers to the RF signal transceiver chip, in mobile phones, and the baseband chip is approximately equivalent, because the baseband is the signal transceiver, modulation and demodulation operations of the chip. But as for whether a certain function is in a certain chip, it is not necessarily the matter. Some mobile phone cpu, integrated application processor, baseband processor, gps and so on.
2, feature phones generally contain only baseband chipsets, alsoIt's called BP. Smart phones, on the other hand, contain AP and BP. The AP, the Application Processor, is responsible for the execution of most applications. The Baseband Processor (BP), also known as the Communication Processor (CP), is responsible for the execution of all communication software.
3, function: the baseband chip is responsible for basic digital signal processing tasks, including modulation and demodulation, encoding and decoding, signal processing and dataData processing, etc. It is mainly responsible for processing low frequency or baseband signals and converting them into higher frequency RF signals. The RF chip is responsible for handling the wireless transmission, amplification, adjustment and demodulation of high-frequency RF signals, as well as receiving and transmitting RF related parameters.
4, the first is the necessity, is connected to the communication transceiver chip (transceiver) and antenna the only path; Its performance directly determines the communication mode that mobile terminals can support, as well as the received signal strength, call stability, transmission power and other important performance indicators, which directly affect the end user experience.
5, the RF chip is responsible for generating, amplifying, modulating and demodulating the RF signal, converting the digital signal into a high-frequency RF signal or demodulating the digital signal from the high-frequency RF signal. Rf chips are usually used in the RF front end of radio communication systems, such as mobile phones, radios, radar and other applications. In general, the baseband chip deals with digital signals, and is responsible for signal processing and modulation and demodulation; The RF chip processes the RF signal and is responsible for the amplification, modulation and demodulation of the signal.
ic is a general term for all integrated circuit chips, ec is a radio frequency chip, ec is a type of ic. The
EC chip is an embedded controller chip used in notebook computers. There are several functions, including keyboard control, touchpad, power management, fan control and laptop battery management. To the average laptop user, the EC chip is invisible and plays an important role in the overall system. EC chips are also known as I/O (input/output) chips, and in desktop motherboards they are called I/O.
EC chips are mainly used in mobile computer systems andIn embedded computer systems, system management functions are provided for such computers. The main function of the EC is to control the computer motherboard power-on timing, manage battery charging and discharging, provide keyboard matrix interface, intelligent fan interface, serial port, GPIO, PS/2 and other conventional I/O functions, the EC may also have SPI interface, can connect Flash ROM (motherboard BIOS) and other SPI devices.
Motherboard EC chip refers to a control chip installed on the motherboard, its full name is "Embedded Controller", can be understood as motherboard embedded controlA surname The role of this chip is to manage various hardware devices on the motherboard, such as keyboards, fingerprint readers, touchpads, and so on. The motherboard EC chip can also communicate with the battery and manage the battery charging and discharging process. The
EC chip is a control chip specifically used to manage battery charging and discharging. The EC chip will monitor the voltage and current of the battery through the battery power detection circuit, and charge and discharge control according to the state of the battery. When the battery is charging, the EC chip controls the size and direction of the charging current to ensure that the battery can be fully charged and prevent overcharging or overdischarging.
1, the RF chip belongs to a kind of analog chip (CPU, GPU, etc., belong to the digital chip), known as the pearl in the crown of the analog chip, it can be seen that the research and development is indeed difficult, but the difficulty is not as large as the CPU and GPU, the latter two exceed the RF chip several orders of magnitude. In this regard, Huawei has given a very good answer, and I will do a detailed analysis later. In 2017n, the domestic RF chip market share is only 2%.
2Rf chip, simple understanding, is a key component connecting the mobile phone baseband and the mobile phone antenna, mainly responsible for the transmission and reception of wireless information, including: filter, power amplifier, RF switch, low noise amplifier and other important components, known as the "analog chip crown pearl". It is expected that this year, Qualcomm RF chip revenue, may reach 8% of total revenue, and will continue to grow in the future.
3, RF chip RF chip refers to the radio signal communication into a certain radio signal waveform, and through the antenna resonance sent out an electronic component, asAs one of the important accessories of 5G, RF chips play a pivotal role in the development of 5G, and are known as the "pearl in the crown" of analog chips.
