microstrip connecting pad

any guidance on how to design the connecting pad between component.
1)for eg, if i have resistor in series with a microstrip opencircuit stub, do i still need a connecting pad in between?
2)For discrete component how to design the connecting pad.

Depends on what you are trying to do. There are standard (jedec I think) dimensions for parts and layout pads so that they can be automatically assembled and soldered without tombstoneing, moving around, and generally wetting poorly. Any part in a < 2GHz role should follow those rules. In general, also, you want the pad to be a few thousandths of an inch too big so you can visually inspect for a good solder fillet.

At higher frequencies, you have to get creative. You might use a small line of solder mask printed across the microstrip line to keep the solder in one place as the board is heated up. For crucial applications, like the resistors in a wilkenson power divider that are very capacitance sensistive, you go with the smallest pads and the biggest gap possible, etc.

hi bliff, i am working in 2.4GHz region.could u pls be more specific to my question.thank you.
