Please note that the block diagram is showing the optional LO of 594 MHz.
But the standard LO is 595 MHz.
Would it be better to modify the block diagram, showing the standard application case, to avoid confusion?
here some additional information regarding the 2.4 GHz 20W Power Amplifier V2.
Attached you find the actual specification.
Further I got some hints by Hristiyan, LZ5HP, today.
Yes, you must connect sequencer output to PTT pin of PA and set the jumper in PA to pos. 1 .
If the connecting cable between transverter and PA has low losses, you can reduce transverter output power by TX trimmer or by reduction of power supply voltage. Another possibility is to solder 3-4dB PI-type attenuator on PA board - there is a free place for this, now the attenuator is skipped by 0-ohm resistor.
You can monitor input drive, output and reflected power on marked pins by a Voltmeter.
Of course, no problem to share or upload the datasheet.
I am using TR2300 Version 1.5
PS Hristiyan is very busy to serve us all as fast as possible.
I am using the Goobay 67269 LNB with 25 MHz TCXO and have not noted any wobbling.
The list should include a pic showing the wobbling of the frequency, before distributing any info regarding wobbling.
yesterday I noted the message by https://twitter.com/MeltdownCore and contacted
Hristiyan LZ5HP, 126 Euro plus shipment 8 Euro, delivery time about 2 weeks plus shipment.
The PA is using an AMPELON LDMOS power transistor -> https://pbs.twimg.com/media/D058XudWoAAJtLH.jpg
SG Lab has started the production of AMP2400.
