Another common cause of low transmit power is the contact between the signal
pin of the SMA connector and the PCB can be compromised if the
connector is over-torqued. If the trace itself is ripped off the PCB,
this is a Problem, but sometimes a blob of solder to shore up the
connection will fix the issue. Try inspecting this connection under a
magnifier to see if any damage is apparent.

For building Verilog code for FPGA x300 series which license Vivado should I
necessary?
Webpack license is enough?
Or do we need a full license?
thanks very much

I'm sorry for the typo, I reformed it For building Verilog code (& generating
bitstreams ) for the FPGA x300 series which Vivado license for a developer is
necessary?
Webpack license is enough?
Or do we need a full license?
thanks very much
