tu jest link do płyty z TRV Wavlab.
Procesor, o ile dobrze go zidentyfikowałem dsPIC 30F511 30I/PT i ATML H704 lub ATML H540 zależnie czy XP czy XN.

ATML H704 lub ATML H540 to rodzaj obudowy i data wydania.
W drugiej linii znajduje się marka chipów.
Najprawdopodobniej jest to dwuprzewodowy układ pamięci szeregowej pamięci EEPROM.
I can see only one solution to install BFHK-2582. To cut the pcb and then to solder (glue) the filter inside of clearance, for best GND connection. In/out 50 ohm microstriplines foil.
One more problem can be the height of filter but is easy to fix.
SMA connectors on the rear side and external BFHK installation is other idea...

Еще одна проблема может заключаться на высоте фильтра, но ее легко исправить.
Разъемы SMA на задней стороне и установка внешнего BFHK - другая идея ...
Удерживает высоту 1,5 мм. Плюс ламинат 0,13 мм. Не знаю, монтировать ли верх плату. А верхняя крышка прижмет фильтрующую пластину к основанию. Или отрежьте фильтр и замените его ламинированным шарфом для фильтра. Вот мой макияж.

Hello All
Herewith my transverter with the XP module.

But I have trouble with the RX path. First tested with 1500MHz IF and 939.5MHz LO but not working. Changed to 1879MHz LO but also not working. After that I tried several LO-IF configurations but no show! Do you have any sugesstions? After my holliday I will test another one from a friend in my setup. I made a powersupply with sequencer to be sure the Negative voltage is first.
Many Regards, Hans Holsink pe1ckk
The RX was broken in the module, ordered a new one, this was working fine on RX

Hi Hans
I hope you are well .
can you try this with RX
- LO - 1810.07 Mhz + 5-6dbm
- IF - 2320,00 Mhz

I can confirm regarding LO & FI selection for XP version. Best Rx gain and Tx spurious rejection are achieved with LO 1808.166MHz/~0dBm and Rx/Tx FI 2350Mhz. The Rx gain seems to flat between 2100...2600MHz and drop under 2100MHz.
Poor results observed with LO 909MHz, Rx gain not very good and abnormal spurious Tx output on spectrum analyzer, even the bolometer power indication and internal monitoring voltage are normal, critical LO level.
More details: https://www.qsl.net/yo4hfu/Link_23GHz.html
The project is under construction, higher FI gain and some small modification are necessary.

Так будет будущий преобразователь на 24 Гц. Только блоки будут стоять вертикально.
Какие будут ваши предложения или комментарии?
