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

Claim 15:
16. The transmission circuit of claim 11, wherein:
the digital frequency equalization filter is expressed as HF1(s)=1/HRF(s), wherein:
HF1(s) represents the digital frequency equalization filter; and
HRF(s) represents a transfer function of the RF front-end circuit; and

the analog frequency equalization filter is expressed as HF2(s)=1/HET(s), wherein:
HF2(s) represents the analog frequency equalization filter; and
HET(s) represents a combined complex filter configured to match a combined signal path filter, the combined complex filter is expressed as: HET(s)=HIQ(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.
