    TEDDY II CIRCUIT DESCRIPTION Power Amplifier Circuit The transmit output signal from the VCO module passes through the amplified (Q110) and amplified by Q121. The amplified signal goes to the final amplifier (Q120) through a low-pass filter. The lowpass filter removes unwanted high-frequency harmonic components, and the resulting signal is transmitted through the antenna terminal.
