In April 2010 i decided to built a new
SSPA for my EME activities. I decided to use 2 small modules
Due to some QRL and other things the project was finished in
So the start of this project was in the time before the new
freescale high power transistors.
The amplifier consists of an built in microcontroller for
RF-power/SWR measurement and overload protection
and the possiblity to remote control the amplifier.
The SSPA has also an built in power supply for external
preamplifier with 24V relay and a built in sequencer.
The receive path is made for the use of a seperate RX Iine
without to modify the used transceiver.
