Hi, my TinySA Ultra is showing all the symptoms of a failed U22. Self inflicted I think so can’t blame the unit.

I’ve ordered a new unit as the supplier I bought it from has offered me a discount.

So as I’ll have nothing to loose I thought I’d have a go at replacing it. I’ve got a hot air soldering unit so lets see.

My question is the description on my preferred suppliers ( CPC ) for a AS179-92LF is “? Switch IC, SPDT, 20MHz to 3GHz, 2V to 5V, SC-70-6?-? AS179-92LF “?

Seems OK

Thanks.? I ask the question as it says "20 Mhz to 3 Ghz " on the data sheet, and most of my work is in the HF bands ( 1.8 Mhz to 30 Mhz ) and the TinySA Ultra itself says " 100Khz to 6Ghz "? I just wanted to make sure this is the right component.

Thanks again.

Dave.

Its is the correct component?

Hi :)

?

If possible, take some pictures of the U22 chip replacement and a few lines of text, was it an easy replacement, etc...

?

Sincerely,

I will document my attempt but it wont be for a few weeks as I’ve got other stuff to do first.?
I will report back regardless of the outcome, but wish me luck.
