PF08109B power amplifier
Dear sir,
This is my final year academic project. i have no such planning as quoted by you.
This is only for academic purpose.
The same problem i had with Modem Design.
Rest assured that i have no such intentions.
Dear sir,
I am using RF section circuit (attached below) in my Mobile jammer project:
1. I am not able to find "50 ohm Micro strip" that is used for impedance matching.Please suggest a solution for "50 ohm micro strip" or any other alternative for impedance matching.
2.Which online RF circuit...

Dear sir
i have posted an image of the circuit in which power amplifier PF08109B is used .
The pin of my concern is pin Vapc(GSM) (control voltage, Pin no.10).
Dear sir,
I am using Hitachi PF08109B power amplifier.
i am providing Vapc (Pin no. 10,Max. ratings: 2.2V , 3mA) to the Power amplifier using a voltage divider circuit.
The open circuit voltage is set to 2.5 but once connected it drops to .9V dc.
Is it a current consideration ?
Why the voltage...
