High Speed PCB Design

[Johnny1010]

Hello everyone I am looking for considerations to keep in mind while designing a pcb(Only double sided available) with high speed signals (upto 100MHz).
What I know up till know:
1)Using small traces to get low inductance and capacitance.
2)Using a complete layer of the two sided pcb as ground plane to act as a decoupling capacitor.
3)Avoid removing any part from the ground layer so that the return current is exactly under the signal current.

Questions:
4) Would using smds be a better option than through hole components and why?
5) If I use smd to provide ground I would have to use vias is using vias for ground and also other connections a good option?
6)What other techniques can be used to minimize the stray capacitances and inductances at high frequency.
7)What is with the transmission line termination and control impedance?
8)Microstrip:what is it ? In case of double sided pcb with one ground layer and the other etched part is this microstrip?
9)What should I do with the power should it be provided on the etched side?
10)Removing the emi.

Please correct me where wrong Please try to answer all it would really help me.

4) No leads. A short wire has parasitics.
5) dunno

Using 250/300mhz transistors like the 2n2222a, here is a simple 100mhz amp.
The board is mostly ground. The board is 1x0.8 inches.

Thanks ronsimpson just wanted to know would it be able to provide a gain of around 4 at 100MHz. Also what is the significance of using a pnp transistor here?

 

[ronsimpson]

The transistors are a little slow for this job. It will do 100mhz with no harmonics.

Gain is set by R5, R6.
The signal turns on the first transistor, that turns on the second transistor, that turns off the first transistor. See if you can see that loop.
Leave R6 & C1 out. I was playing with peaking.
