Motorola Chip

[chambersjr]

Hello all. Wondering if anyone has came across these before and has any data on market price and/or yields? I'm not qualified to refine so will be selling these as is.

 

[chambersjr]

Surely I'm not Christopher Columbus. Anyone w/ atleast a price guesstimate?

It may be the fact you used a zip file to show your pics. Not convenient for many. I would value these based on the base metal weight. Some are very light, like titanium or some sort of aluminum alloy, some are very heavy, tungsten copper alloy. Light ones are higher in value, $40 to $120 a pound depending on base metal.

Thank you for the reply.

I tried to add the post w/ photos via iPhone & couldn't get the add image option to work. Was trying to hurry & just ended up adding via zip on desktop. Anyway, appreciate the feedback. The ones I have all seem to be 23-24g. I'm assuming that would be considered "heavy". I havn't filed into the base but I will.

Those look similar to the RF power transistors that I harvest from cellular and radio equipment. They do contain beryllium oxide in the white areas but these are extremely high grade scrap. 25 g each is huge for these. Do they have ceramic lids that were removed? What did they come from?

those are Rf type power transistor types,Motorola not only used them for their own radios but also in Nortel telecom amplifiers where there is usually 8- 10 per unit, they have gold bonding wires connecting the various hybrid substrates,those are probably gold plated copper bases,newer ones went to aluminum alloys,sometimes the traces on the ceramic are solid gold..they are hi-value scrap and that estimate is right in the ballpark at 40-120/#-hope you have lots to sell

How much does one of them weigh?

Average 24g.

 

[chambersjr]

No. They have a plastic lid or protective cover that pops off exposing the traces that show in the photos.

What did they come from?

Motorola 800mhz power amplifiers

chambersjr,

Those are impressive. I have stripped many 800 MHz Motorola radios and have never found Power Transistors that large.
Do you know what technology radio these are from? PCS, TDMA, etc...

Thanks,

Keith

looks very similar to the ones i saw up for bid on ebay...

 

[Emporio]

I have some similar ones. This one is with what I think is silver threads and the others that I have is with gold.

 

[g_axelsson]

If the wires are silver colored it is probably aluminum. Put a drop of NaOH on it, if it is aluminum it will dissolve in the lye.

I put two drops of NaOH on it and it started to fizz a bit, but nothing happened to the threads.

if you haven't sold them I'll take them
