Re: macthing mixer?
It depends on the operation frequency and dimension of your circuits.
If you are doing IC design for RF, typically the dimension of the metal trace delivering your RF or LO signal to mixer is much smaller than the wave length so you may consider it as a voltage signal and...
low inductance resistor 0402
You need to check with the specific 0 Ohm 0402 device vendor for the exact specifications. Murata or Johanson devices could have different performance.
Personally, I think the inductance is less than 0.1nH at 1GHz and may rise to 0.3nH at 5GHz. However, the SFR...
laser diodes with different laser wavelength label emits laser at different frequencies. You need to check with you application system whether the difference is tolerable or not.
Re: RF transceiver
I think you need to determine at what frequency you want to operate your device or you are allowed to operated devices.
Most possibly if you want to run your system in unlicensed 400MHz or 900MHz ISM band, I think lots of IC vendors have off-the-shelf correspoding devices...
1db compression point
Well, I think u did not catch the point quite well.
1dB compression point is the power level where the amplifier's gain is compressed by 1dB.
For example, a LNA's gain is 15dB at small signal input
while the input signal increase, the gain will reduce due to non-linearity...
is it due to the NQS effect? and the total resistance u seen is not the physical resistance alone?
I also have this doubt and wish some one could give the right answer
best regards
you can try to use design->plot->submit
and in the plot option, select save it to a file with a suffix of .ps
then copy it to some media or ftp from the printing office to the workstation to download the file and double-click it (Install Acrobat first), then Acrobat will transfer the file format...
