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.
The regulated power supply circuit delivers the regulated 3 VDC for the drain circuit and the 7660 IC produces a negative bias for the gate circuit. R5 sets the drain voltage to+3 V and R3 sets the gate bias. Typically, the drain current is about 10 mA.
