The main indexes of RF chip include operating frequency, frequency band width, signal gain, noise factor, linearity, dynamic range, power supply voltage, power consumption, etc.
The operating frequency refers to the frequency range in which the chip can work, and the frequency band width refers to the data bandwidth that the chip can transmit in this frequency range.
The signal gain is the signal magnification that the chip can provide, and the noise factor is the ability of the chip to suppress the signal noise.
Linearity is the output stability of the chip under high power signals, and dynamic range is the maximum signal amplitude range that the chip can handle.
Power supply voltage and power consumption are the electrical characteristics of the chip, which affect the service life and reliability of the chip.
The main test indexes of RF chips include standing wave, insertion loss, center frequency, bandwidth, in-band fluctuation, out-of-band suppression, group delay, etc.
In the mobile communication system, the bandwidth of the RF front-end chip is generally defined by the carrier frequency, such as the current common mobile communication system with 100 MHz as the benchmark. The above information is for reference only, you can consult relevant research materials for more information.
The index requirements of RF chips are to challenge the process limit, which requires a lot of innovative circuit structures, such as noise cancellation, cross-modulation component cancellation, dynamic bias in order to improve the efficiency of the power amplifier, and sometimes in order to reduce power consumption.
