Question 6A393

Adjusting a multi-stage transmitter follows the logical path of the radio frequency (RF) signal. The **master-oscillator** is the initial source of the RF signal; it must be stable and producing the correct frequency before any other stage can operate properly. Once the oscillator is set, the **intermediate amplifier** can then be tuned to efficiently amplify this signal. Next, the **final amplifier** amplifies the signal to the desired transmission power, requiring it to be tuned to the operating frequency and matched to the preceding stage. Finally, the **antenna circuit** is adjusted to provide a proper match to the final amplifier's output, ensuring maximum power transfer from the transmitter into the antenna for efficient radiation. Adjusting stages out of this sequence would mean attempting to tune an amplifier without a proper input signal or matching an antenna to a final amplifier that isn't yet operating correctly, leading to inefficiency or potential damage.
