Hi Andrey.  I got a notice that my Hittite rep has 2 samples.  I'll
try to connect them this week and will ship them to you as soon as I
get them.

Hi Robin.
Thanks for the good news.
When this happen, please send me by e-mail a copy of the postal receipt.

Best regards,
Andrey Sviyazov.
P.S.
As I remember, you also offered few extra samples ADF4350, it would be
absolutely great :)

Hi Robin!

I have a good news.
I was received 10pcs samples of HMC830LP6GE, it was unexpectedly too fast.
Sorry that I disturbed you about it.

Best regards,
Andrey Sviyazov.

Subject: Fwd: UmTRX UHD firmware
Message-ID: <CABmJbFWXY3ca_gmQ6ycyyYtBkKKMZLXSnVgdrtZk3TweLUdTgg@mail.gmail.com>

Hi all,

Attached is an UHD-based FPGA image for UmTRX. We've just fixed one
last bug in the Tx chain and I think it's a good time to let everyone
know about the progress. Corresponding host software could be built
from the 'fairwaves/umtrx-dboard' branch in our repo:
https://github.com/chemeris/UHD-Fairwaves/tree/fairwaves/umtrx-dboard

Notes:

 1. UHD code doesn't touch LMS configuration at all. So all LMS
configuration should be done before you run UHD tools with the help of
'umtrx_lms.py' utility. This includes turning on LMS Rx/TX modules,
tuning, calibration, amplifiers configuration, etc:
https://github.com/chemeris/UHD-Fairwaves/blob/fairwaves/umtrx-dboard/host/utils/umtrx_lms.py

 2. So far only Tx has been tested and is known to work fine. Rx
testing is our next target.

 3. LMS works at 13 MSPS and UHD allows you to go up to this rate.
Interpolation in Tx chain is known to work well, so you could also use
fractions of that rate, like 0.270833 MSPS ;)

 4. It's strongly recommended to tune VGA1 DC offset in a LMS before
using - it reduces LO leakage by very nice 25 dB.

 5. We still have to figure out how to tune I/Q balance in UHD.
Without calibration LMS doesn't perform very well. I know it should be
pretty straightforward to do, but we have to figure out how.

Alexander Chemeris.

Hi Andrey.   I'm back from vacation and will mail a package with 2
more Hittite HMC830LP6GE and 3 ADF4350BCPZ chips today and will e-mail
the tracking number.

JFYI:
