Powerful AM Transmitter
This is the circuit diagram of powerful AM transmitter which use ceramic resonator/filter of 3.587 MHz. Resonators/filters of other frequencies such as 5.5 MHz, 7 MHz and 10.7 MHz may also be used. Use of different frequency filters/resonators will involve corresponding variation in the value of inductor used in the tank circuit of oscillator connected at the collector of transistor T1.

1296 MHz RF Amplifier using NEC70083
Here the Radio Frequency (RF) amplifier circuit design for frequency 1296 MHz.
By using an NEC70083, this 1296-MHz amplifier delivers about 17-dB gain and around 1- to 1.5-dB noise. It is assembled on a G-10 epoxy fiberglass PC board. Use the layout shown because this is very important for correct performance.
