Hi,
I'm developing a power amplifier whit BFG520 at 915 MHz
these are the characteristics that I have reached:
Vcc=5V
Icq=5mA
Pin=9 dBm
Pout=19 dBm @ 33mA of Ic
these parameters are valid with load of 50 Ohm.
when disconnects the load and i open the output of PA the Ic goes at about 70 mA!!!
how can I do to prevent this?
about what parameters should I work?
Thanks.
