Sd1446 amplifier

POB6612DX Liner amplifier by JA1BOP: リニアアンプの泣き所は、とにかく電源の確保が難しいことです。アマチュア無線家の人口は減少しているとは言えまだまだ沢山います。しかし、素人無銭家にとって28Vだの50Vだのと電源を確保するのがむずかしい。

SD1446 - Transistor, 27-88 MHz, 0.380 Flange, ST Micro (NOS) The SD1446 is a 12.5 V Class C epitaxial silicon NPN planar transistor designed primarily for land mobile transmitter applications. This device utilizes emitter ballasting and is extremely stable and capable of withstanding high VSWR under rated operating conditions.

- Jan 04, 2015 · The sd1446 are rated at 70 watts at 12.5vdc. Maybe he had the colts turned up to 15vdc. That amp will not last long at that voltage but may take a short key up to show some big watts. Don't believe the hype. That amp should be rated at 250-300 watts. Anymore than that is just pushing the transistors beyond it's designed limits. It will ...
- I have the 3.10 version of this amp and I am trying to adapt your mod to it. I understand the Diode goes between the SD1446 leg, and ground (band toward the ground), but the resister, does that go between the SD1446 and switched 12V? It seems the 3.10 version of the amp simply switches a ground for power on.

Sep 18, 2010 · Now what I need is a set of four sd1446. If possible quad matched, my RM kl 500 "facelift 2010" brand new amp has gone bad after two weeks. It had 7 watts input/exciter and v low swr and a beefy supply cable with the poxy fuses inside wired out and a single fuse fitted for more dc input and less volt drop a fan was fittted. The amplifier is only a part of an equation like that. Voltage, antenna (s), reflection, impedance, so many variables to test something with viable results in that manner. The 2879 and 1446 "sound" no different on air when used in a similar configured amplifier. 2879s have nearly double the rms capability as the 1446.
