What TX amplifier do you plan to use?

-
BTW, what is the original connector?
You can have a look at post #179.
On this similar board the connector types are MMBX and AFI.

4Z5YR: i took the following steps (not in full detail)
removed ALL filters/isolators/circulators from the PCB and made straight connections
removed the first stage because the driving pwr was about 100-800mW so no first amp needed
modified the finals from doherty to manual IDq setting (the automatic IDq on the second driver was working ok so i leave it)
installed a SMA input and N output connector where the output circulator was.
carried out a lot of snowflaking and resizing pads on the PCB to get best gain (takes long because you have to remove and
reinstall the cover after each try)

Hi, did you measure current consuption of PA module with 100W output? How many Amperes did you get?
Thanks!

DB8TF and DM4DS
Thank you both for information. After modifying my the same unit takes about 11A with 28V from PSU. With 100mW input power, output is about 100W (may be some more). I'm using it for WB operation. With 0.85m offset dish and 333kb/s signal, amplifier provides 9dB over noise on web monitor.

Dear all,
I have also built one of the amplifiers with the MHT1008N based on the design by DJ0ABR and DC1RJJ.
Enclosed you can find my measurement results: 2.4GHz medium power amplifier MHT1008N
Thank you very much to Arved M0KDS for providing the populated PCB.
Kind regards

Dear all,
I also finished building an amplifier based on the Andrews module with the MRF21045.
Special thanks to DK5DN for publsihing his modifications which worked perfectly well for me.
You can find my setup and the results here: Modification of Andrew AP module with MRF21045 for 2.4 GHz
Kind regards
