The transceiver circuit generates a radio frequency (RF) signal(s) from a time-variant modulation vector and a power amplifier circuit(s) amplifies the RF signal(s) based on a modulated voltage. The transceiver circuit is configured to apply an equalization filter to the time-variant modulation vector to thereby compensate for a voltage distortion filter created at the output stage of the power amplifier circuit(s). In embodiments disclosed herein, a calibration circuit can be configured to calibrate the equalization filter across multiple frequencies within a modulation bandwidth of the power amplifier circuit to generate a gain offset lookup table (LUT) and a delay LUT. As a result, the equalization filter can be dynamically adapted to reduce undesired instantaneous excessive compression and/or spectrum regrowth resulting from the voltage distortion filter across the modulation bandwidth of the power amplifier circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Equalization filter calibration in a transceiver circuit","description":"Equalization filter calibration in a wideband transmission circuit is provided.
