hi,
the power trend switching regulator is just a gimmick. You can use a standard 78xx, too.
------
Important: ... building jammers is no piecework! Try to build one by yourself and you will see it´s very hard. You even cannot expect a ready well-working circuit, there is always something buggy/ to improve. And so you have to spend a lot of time with it...

Hallo, auf den ersten Blick ist diese Schaltung narrensicher ... 1,9V sagst du... merkwürdig.
Ich habe mir das Datenblatt vom MC1458 angesehen. Was mich furchtbar stört:
-Der MC1458 HAT KEINE Rail-to-Rail Ausgänge! Wie soll der Ausgang auf null gehen, wenn diese Schaltung einen 08/15-OPAMP enthält?
- Wie zu Teufel kommen die bei dem Messverstärker auf eine Bandbreite bis 10GHz?!? Einfach lächerlich, diese Angabe. Der OPAMP MC1458 hat max. 1MHz. Ok, letztendlich wird nur Gleichspannung verarbeitet und auf einem Messgerät angezeigt, aber trotzdem... tz tz tz.
[ - Und nicht mal richtig rechnen können die, die Verstärkung geht von 1-121 ;-) ]
----------------------- Der Richtkoppler gefällt mir. Da ich nicht viel mit Funk zu tun habe, kannte ich bis jetzt sowas gar nicht ;-) Bestechend einfacher Aufbau, wie er funktioniert ist völlig klar :-)
MfG Richard
