Classification: CPC H | IPC H

Claim 12:
13. The blocking signal cancellation low noise amplifier system as claimed in claim 12, wherein the comparator is used to compare the DC bias voltage signal VB2 with the preset reference voltage signal Vref, wherein when the DC bias voltage signal VB2 is smaller than the preset reference voltage signal Vref, the comparator outputs a low-level control voltage VEN and a high-level control voltage Vblk as the first switching signal; when the DC bias voltage signal VB2 is greater than the preset reference voltage signal Vref, the comparator outputs a high-level control voltage VEN and a low-level control voltage Vblk as the second switching signal.
