Can anyone share some basic info on design of radio transmitter-receiver? I want to be able to create one by my own - if possible, pls. include piece parts(tipong electronic enthusiast) and short description of the function of each modules(in the PCBA).Thanks!
As an ECE instructor, i believe mas madali maggawa ng FM or AM transmitters for students. you can design one using 3 or more transistors. Marami schematic sa internet pero wala calculations other than just descriptions.You will need a thorough knowledge on transistor amplifiers (common-base, common-emmiter, voltage-followers, multitransistor amps), oscillator circuits, maybe power amplifiers, also freq. response of transistors.you will need an oscilloscope, 2 channels preferably. If you are building an FM transmitter, you might need 100-Mhz oscilloscopes. kung am transmitter, gamitin mo 4-quadrant modulator IC para madali connected to a power amplifier.
