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...

true ... true ... everything without expensive equipment.






@ richy_64 .... du ich habe da einen Messverstärker für den
Richtkoppler im letzten Bild. Er verstärkt das Signal etwas,
um es auch bei einigen Milliwatt anzeigen zu können.
Die Schaltung ... 2 OP's nichtinvertierend kaskadiert.
Verstärkung 0 bis 100 ... bekomme aber immer eine Ausgansspannung ,,, auch wenn ich die Rückkopplung auf
eins setzt ... in diesem Fall ... 1.9 Volt ....!!!! Ich hatte zwar
2 Monate OP Lehrgang und bin eigentlich ein Gott in diesem
Fach ... aber ich bekomme die Spannung nicht runter.
Der Eingang ist natürlich auf Masse. Der OP hatt keinen Offset.

(MC1458)

Wenn das so ist (Premium-Edition)
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
