Consider the microstrip line as an capacitor, with whatever is radiating as one plate and the microstrip line forming the other side of the plate (and negliect fringe fields, especially if you put the radiator close). If you could estimate the capacitance. And then the capacitance between the microstrip line and ground, you could model the noise. Or if you ...

You can implement this with only one resistor, or more exactly, a 3 pad layout, where the resistor can be installed horizontally or vertically. This way, you save about 2pF of parasitic capacitance, which is critical for a 2.4GHz design. Keep the trace to U3 as straight as possible, you want to minimize the number of bends on an RF trace. Keep the trace to ...

You can't directly connect those two using a breadboard. They are SMD parts, so you can't connect them to a breadboard. You can probably get a breakout board that you could solder the AS3933 on to. There are standard parts that should fit, though they might be difficult to find. The CAS143 has its own peculiar layout for the connections. You won't find ...
