I was wondering, if there is a commercial 2.4GHz antenna how would it perform in harmonic frequencies?
Here's an example 2.4GHz monopole antenna.
**broken link removed**
I checked the specs but it doesn't give any info on harmonic frequencies.
Based on what I learned in basic antenna theory...
while searching through 0ohm resistors, I noticed that all the datasheets that I came across do not have any information about frequency response of the resistor.
I did read a comment somewhere saying that 0ohm resistors tend to work well even at pretty high frequencies but didn't give a...
oh I see
now I get it. the word 'jumper' was used just because 0 ohm res. are widely used for 'jumper' purposes.
and since for 0ohm, you can't get negative tolerance but only positive values for it, the datasheet prefer to write down 'max res.'.
I checked the datasheet as you said, and I found...
while searching for 0ohm resistor to use at 2.4GHz, I came across a search result like the image below.
Why the word 'jumper' as a value for tolerance? What does this mean? Is it somehow related to 'jumper wire'??
Re: how to get design variable into calculator in virtuoso?
Brilliant idea for getting dc values... but in this case, I would like to get the 'frequency' value... I don't think the same method can be used in this case.
I have setup a simulation with a design variable.
With the simulation result, I wish to make some expressions that uses values of the design variable.
For example, I currently have a design variable named 'freq1'. How do I utilize this value in the calculator/expression?
I've tried...
I have done a pss simulation where I can check the 2.4GHz power at a port. However, I would like to make some kind of expression that will display the value of power at 2.4Ghz at ADE's Output value column.
this is the pss result that I have. The value that I would like to see si the one at...
when I soldered some SMD components, it looked like the solder mask got a little burnt and these brown sticky stuff was created around the pads. Unfortunately, these unknown residue covered nearby pads that prevented me to solder components to it.
Could anyone identify was these stuff are...
hmm.. your answer kind of answers some part of my question but it also confuses me again on the other.
okay you said the length doesn't necessary have to be quarter wavelength to provide good coupling.
despite this, you still mention that the coupler is 'good' to have a length equal to quarter...
for directional couplers which is nothing but two parallel microstrips adjacent to each other, I can't understand why it has to be quarter wavelength.
My guess is that since coupling is merely interacting with the other microstrip through E, H fields, there isn't any need to be quarter...
Thanks for such an insightful answer
I really needed to know the external case where if the frequency is the same as the onchip inductor, then the external magnetic field can change the L value.

Thanks for the reply
I really should check out the equations relating L with...
I'm confused about the influence of inductive coupling.
Say there's an on chip inductor.
Would the L value of this onchip inductor change if some external magnetic flux is applied?
On one thought, the L value seems to be a fixed and fundamental value that cannot be changed once designed.
On...
