Berex - Korean maker of RF parts...

[Clifford Heath]

Just a heads-up. I just came across
<https://www.berex.com/MainProducts.aspx>. They seem to make a nice
range of RF parts, including some in categories that are getting a bit
sparse elsewhere.

Some here might find them useful. Others might have already, and wish to
comment.

Mesfets! But looks like bare die.

Interesting. I don\'t think I\'d heard of Berex before ?

They also have packaged power pHEMTs, but they\'re in ceramic macro-X
package$$$. Interesting though.

Yes, interesting. We have a couple of older products that use mesfets,
but they will soon be gone, replaced by GaN.

Their small phemts are not unique; there are a few other sources.

I hadn\'t heard of them either. Yet, their home page says they\'ve been
around since 2003. They have offices in Silicon Valley and in Santa
Ana.
<https://www.berex.com/ContactUs.aspx>
Very little press since 2011:
<https://www.berex.com/News.aspx>
<https://www.berex.com/PressReleases.aspx>
Only the most recent news articles were in RF journals and web sites
that I read. Only 2 US patents. The other patents are in South
Korea, but do appear on Google Patent search.
<https://www.berex.com/Patents/Patents.aspx>
They recently bought OctoTech, which makes IoT front end modules. I
found only one announcement online:
<https://compoundsemiconductor.net/article/110757/BeRex_buys_OctoTech>
I couldn\'t find any financials. I think we may have found a good
example of how to maintain a \"low profile\".

Their main products were chips and wafers, so an issue with
identification . . .

Was unaware that they were starting to package in plastic,
with nice, short, full part numbers on SOT89.

NATO using plastic from S.Korea?

I have just tried a Mini Circuits SOT-89 part on 10 GHz.
What a lame thing, something with xxx-123! Not much gain left
over there.

The ADF5356 has an output frequency doubler from 6 to 12 GHz.
Fundamental suppression is a joke. After the SOT-89 amplifier
there was more fundamental than intended output.
A micro strip notch filter and a AD/Hittite HMC451LP3 did
the trick.

I have also made a 9-11 GHz micro strip band pass with ADS
on Rogers TMM6, intelligent component auto-generation style
without even using the Momentum electromagnetics sim.
First try was usable, although I changed the gap in the i/o
transformers from 3 to 5 mil by hand to keep the board producer
from complaining. That introduced some ripple that could be seen
in the equation-based simulation. I wished I had a license myself!

Transfer to Altium via DXF produced a skeleton only. Gerber transfer
worked better. I could make an Altium library part from the filter
via Gerber inport.

I can just take the filter from the lib into the schematic now, and
in the corresponding layout the properly placed dozen of ustrip lines
pop up and can be moved and rotated just like all other part decals.
1.5 dB pass band loss. I like it!

If GVA-123+, there\'s supposed to be 12dB, with a couple GHz to spare.

Maybe they just opened a US office in 2003 ?
