Thanks for the tips, this is what I was looking for. The ATC Typ

thank you Achim

Hallo Achim

It,s for the HF path, i have found a Johanson Trimmer whit 1,4 - 4 pf in my Boxes that works very well and have 250 volt Spannungsfestigkeit. But what for Typs nid i for fest Condensator,s

Greats Klaus

I work with BU500

I want to modify a couple of UMTS PAs and I need SMD Cs 0805 What do I need for SMD Cs there are many different types NP0 and so on and how much voltage do they have to have

The PA works with 28 volts

Especially for the output circuit

Thanks Achim for this description, I've been looking for something like this for a long time.

Thank you for your answer Alessio.

I'll try it.

Thanks Klaus

I start with the Pluto in DVB-S but with a higher bit rate the pluto starts to produce intermittent transmissions.

The PC is an i7 4 x 3.6 Ghz 16mb Ram and WIN 10 64 bit.

I use DATV-Express for sending. The frequency of the Pluto is expanded and the 2nd core is activated. The Firmware is 0.31 from analog.com

Only with 250 or 500 kbps the transmission is OK.

The Pluto is connectet to the USB 3 port without an external power supply.

What is my Problem?

Hello

I am also very interested in this project.

Please can you give us a how to

Thank you very much for your effort and nice to meet you here.

The Xinger can probably only tolerate 25 watts.

I hope it does not burn.

I would get 40 - 50 watts for DATV

My PA has not arrived yet.

I'm curious if we get something out of the PA

Hello

thanks for your description, I also ordered one. How did you solder the SAW filters and the other things out? Next up someone wrote that it is hard to solder because the base plate absorbs the heat strongly. Maybe OH3WE writes us how far he is
with the PA.

hello together I am also interested in Es'hailsat

I have a PA with MRF 21030L I use for DVB-T makes a maximum of 14 watts at 2.4 watts input at 27 volts at 2370Mhz

Have the PA on a HAM market bought by someone who has Modified for 13cm look what he did. I think your MRF is more powerful

I hope it helps you a bit

For Uplink to Es Hail i want use another PA
