The circuit Tv transmitter very simple

The circuit is very simple, it just has three transistors, but the transistor types have been changed for VHF/UHF transistors. You can use 2N2369, BSX19 or BSX20, or any small signal transistor with an “ft” of typically 400MHz or more. The transistor DC biasing is a little more tolerant to varying transistor types than the […]

How to solder a very ideal for assembling electronic components?

SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is […]
