Hi Rob --

Thanks for the pointer. I should have been more detailed -- I was hoping to find the same model number as I'm building several copies of a signal chain and wanted to use the same amp block in each; I already have a couple of these units and know they'll do the job, so was hoping to just snag a couple more.

And, what was attractive about this unit for my application is that the P1dB is about +25dBm which is ideal for the driver application I have. Don't need a lot of gain, or frequency above VHF.

But thanks for the lead, it's appreciated.

John

John,

How about these on EBay, Item : 110803140186

Cheap and plenty in stock.

I've just ordered 4 to experiment with.

Subject: [time-nuts] Looking for Harris/Qbit amplifers

Several years ago eBay offered some nice amplifier blocks that went up to
500 MHz with about 10dB gain and 25dBm maximum output.

The part number on the unit is Harris 0130-211013, but they were sold as
"Qbit 512".

I got a couple back then, and would now like to find two or three more to
use in a project.  Of course, the eBay source is long gone.  There's not
much in the way of Google hits other than the page I put up with some test
results.

Anyone have any of these squirreled away, or know where any might be found?

Thanks,

John
