TRF receivers were one of the first types of AM receivers. TRF receivers have three stages: RF, detector, and audio. EXCEPT FOR ONE, the following are the disadvantages of TRF receivers. Select your answer. The carrier recovery and demodulation processes both need the use of an oscillator. When adjusted over a wide range of input frequencies, the bandwidth is uneven and fluctuates with the center frequency. Because the transformer-coupled tank circuits in the RF amplifiers have nonuniform L/C ratios, the gains are not uniform over a large frequency range. The enormous number of RF amplifiers all tuned to the same central frequency causes instability.
