Center project

5G RF receiver: the project achieves the functional integration of 4.4GHz ~ 5GHz RF of receiver IC. This

RF receiver is designed based on 70MHz of medium frequency, the chip totally integrates low noise

amplifier LNA, image rejection drop conversion mixer, medium frequency buffer, pressure control oscillator

 VCO, frequency synthesizer and some others auxiliary circuits. The dynamic gain of its internal programmable

medium frequency amplifier is 60dB; totally programmable fraction N phase-locked loop (PLL) can

 be programmed as any frequency through three-line bus; and Sigma-Delta fraction synthesizer enables

 shorter establishment time. The chip can work in the temperature scope of 40C ~85C.
