ANDREWS ex-UMTS SSPA

In this section I will describe the modification of an ANDREWS UMTS unit to be used for 2320Mhz.

There are several Radio Amateurs who already did modify this type of SSPA.

[ DL4MEA, OK3RM, SP6JLW,OE3EFS]

 

The main PCB contains two independent sections, which will be worth to modifiy for use on 2320MHz.

 

 

First the smaller PCB will be investigated, to gain experience.

After succefull results the modification of the High Power Section will be described.
