Versterker RF2126 RF-eindversterker 400-2700 MHz 2,4 GHz 1 W versterker met koellichaam

Die Platine funktioniert. Ich musste aber noch Wärmeleitpaste zwischen Platine und Kühlkörper auftragen.Die fehlt nämlich.Konnte man erwarten, ist aber kein Showstopper. Mit Wärmeleitpaste ist gemessen an der Temparatur des Kühlkörpers überhaupt die Wärmeableitung erst richtig gegeben. Bei dem Preis , OK! Aber eben keine 5 Sterne.

This arrived with the bias tee inductor (L2) missing, and the input SMA connector shorted. I had the parts to hand so I just repaired it rather than returning it, but the quality control is very poor. Having repaired it, it works more or less as described. Peak output for me was at 5V rather than 6V supply, and it was best at around 1800MHz - at 400MHz it has nearly no gain, and similarly by 2.7GHz. This could probably be altered easily by changing the matching capacitors on input and output.

Buono la PCB, l' amplificatore é sicuramente non collaudato infatti il connettore SMA di uscita non era saldato e un condensatore ugualmente non saldato. Dopo le riparazioni ha continuato a non andare. L'assorbimento era di 0 ma. Riconsegnato.

Nessuna problema riscontrato. A 1,2 GHz la potenza è circa 1 watt su carico fittizio.

restituisco, non funziona
