Oscillator in Microstrip

[erickson]

I have built the microstrip oscillator design and I will generate the layout. However, I have some important doubts about the microstrip design, and I want to solve before I will go forwards.

I attached a picture of my microstrip design, to understand my problem easier.
My main questions are related with the MLIN(50Ohm, L=90deg) and the Resistance(50Ohm), I point it with the sign '???' at the picture:
- Is the MLIN at the correct position, or should it be before the resistance?
- When I included the MTE at the microstrip design, I added the mentionated MLIN (to do the adaptation of the MTEE). For this reason, Should I keep the resistance at my design?, or otherwise, Should I delete it? Because, maybe the new MLIN replaces the resistance, and this resistance must be delete.

First of all, you need some MLIN before your resistor in layout, otherwise you can't solder it. Is this 50 Ohm resistor for matching? If this TML is really 50Ohm and the resistor is 50 Ohm, length doesn't matter (in ideal case).

yes, yous should delete the R5, and use term instead of port, and for MTEE, add a MLIN for each branch

OK! I will deleate the resistance. However I am wondering, if i want to generate the layout, Should I add Term instead Port????

Term will not be in the layout. Ports will be in the layout for em simulation. You can use your schematic with ports as sub-schematic. And use terms for simulation.
