i decided to check the datasheet of my inductors and chose the inductor value with a resonance frequency above my operating frequency and i use that value to solve for capacitor. now i have a lower value of 33nH and cap of 0.56Pf. what i am not sure of is if my inductor can still act as an rf...
@Owis,I just discovered that my inductor is behaving like an idea inductor which is not the same in the real world. Could you please tell me how to deal with the self resonance frequency of the inductor. my frequency ranges from 1 to 5GHz with design frequency of 2.4GHz
Thanks so much, i am going to try it nah

Owis. that means the inductor reactance is 10times the impedance(500 ohms or more), and the capacitor reactance should be 10% of the impedance (5 Ohms or lower)
bias tee circuit problem for balanced amplifier at 1 to 5GHz. Please help me check
Please i am trying to design a bias Tee circuit for my balanced amplifier design operating at
the frequency range of 1 to 5GHz with centre frequency at 2.4GHz. what value of impedance do you think i can use...
please i need to create a 1mm space inside a microstrip line in the AWR environment, This space is needed for the capacitor.
I need this space to come out in the pcb without me cutting the 1mm space on the pcb. Any help on how to go about it in the layout

Thanks so much RCinFLA, In this design, the amplifiers are identical but inorder to get a good input and output return loss, the balanced amplifier is design for less gain than that of single amplifier . since a single amplifier has bad input and output return loss the balanced...
Thanks so much BigBoss, it is working perfectly after optimization. The gain is increased to 10dB from 2 to 3GHz band. The problem now is
how to bias the two transistor used in the design and choosing the best bias techniques.
please i am trying to design a balanced amplifier, the branch line coupler used is perfect. i am using double stub as my matching
techniques, but i think that matching network has no effect on the amplifier design since the branch line coupler had cancels all reflections.
The problem now is...
