Patent ID: 11942899
Assignee: QORVO US, INC.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. The transmission circuit of claim 3, wherein the digital frequency equalization filter is expressed as HF(s)=[1/HEQ(s)]*[1/HRF(s)], wherein:
HF(s) represents the digital frequency equalization filter;
HET(s) represents a combined complex filter configured to match a combined signal path filter, the combined complex filter is expressed as: HET(s)=HEQ(s)*HPA(s)*HIV(s), wherein:
HIQ(s) represents a transfer function of the signal processing circuit;
HPA(s) represents a voltage gain transfer function of the power amplifier circuit; and
HIV(s) represents the voltage distortion filter created on the output stage of the power amplifier circuit by coupling the power amplifier circuit with the RF front-end circuit; and

HRF(s) represents a transfer function of the RF front-end circuit.
