50 ohm load

50 ohm loadIt is often very interesting to have a matched dummy load of 50 Ohm.
Indeed it allows to adapt a PA output, or to make power measurements etc..
Several parameters are studying for a proper charge:

  • power loss
  • value and SWR
  • etc.

The oscilloscope

Analog and digital oscilloscopeThe oscilloscope is a measuring instrument widely used in electronics. It provides a measure of signal in the time domain.
Using the probes you can view the signal at a point in a circuit.

Choosing heatsink

Choosing heatsink

What kind of heatsink you choose?
In electronics, most heatsink you will find are black anodized aluminum. Some are pre-drilled, others are rough casting. Course it is more convenient to choose a model that can serve as pre-drilled soon acquired, if the component to be cooled is provided with one or more holes. Undrilled models are preferred when it comes to cutting the heatsink to a size that does not exist in any given market. The different models are available all have a common characteristic that should not scare you, and that is the thermal resistance, Rth denoted. Remember, this thermal resistance is expressed in ° C / W and represents the temperature rise per watt dissipated. Over the heatsink is small, and its thermal resistance is high (at least it will cooling).
