Semiconductor radio frequency abbreviation RF, RF is RF current, is a kind of high-frequency AC electromagnetic wave, is the abbreviation of RF chip. Radio frequency chip refers to the radio signal that converts radio signal communication into a specific radio signal waveform and sends it out through the antenna resonance. Electronic components. The RF chip architecture consists of two parts: receiving channel and transmitting channel.
For the existing GSM and TD-SCDMA modes, if the terminal adds support for the frequency band, its RF chip will increase the receive channel accordingly, but whether the transmission channel needs to be added depends on the relationship between the new frequency band and the channel. Original frequency band, group.
For a mobile communication system with receive diversity, the number of RF receiving channels is twice the number of RF transmitting channels.
This means that the greater the number of LTE bands supported by the terminal, the number of receiving channels for its wireless chip will increase significantly.
