I have joined this forum just now. I am an Electronics and communication engineer, from Gujarat University. I am in 8th sem. I have got a project to design the RF combiners and splitters of the Power amplifier module (1 to 3 Kw), with micro stip lines.
I needed some help on this subject. Where could I find the basics and design issues of microstrip line designing? If any body has the guidelines to this project please help me out.
Thank you for your kind Attention..[/b]

I have got the specifications for designing now.
The specifications are as follows:
Frequency : 88 to 108 MHz
Division : 2 way (0°)
Insertion loss: 0.1 dB
Isolation port to port : 25 dB
Return loss (i/p - o/p) : ≥ 25 dB
Impedance (i/p and o/p) : 50Ω
Divider : 100 W capacity.
Combiner : 1kW capacity
Glass epoxy material to be used : 1.6 mm for Divider section.
2.4mm for Combiner section.
Moreover the Z0 = √(100 + 50) = 70.71Ω
Here Absorber resistance, R = 100Ω
And I/P or O/P impedance = 50Ω
For center frequency of 97 MHz : λ/2 = 644 mm
Please Tell me how do i approach with this designing what should be my first step?
Thank you for your kind attention.
