Abstract
The present invention discloses a transmission circuit having output power compensation mechanism. A base-band circuit receives and processes a digital input signal to perform conversion and amplification according to at least one gain parameter to generate an analog output signal. A frequency up-converting circuit performs frequency up-conversion on the analog output signal to generate an RF signal. A RF amplification circuit amplifies the RF signal to generate an output RF signal to an antenna. A temperature monitoring circuit monitors temperature of the RF amplification circuit to generate an instant temperature value thereof. A calibration circuit increases at least a part of the gain parameter when the instant temperature value makes a power of the RF amplification circuit decrease and decreases at least a part of the gain parameter when the instant temperature value makes the power increase.
