I m would to study the design of a GPS sytem,
what is needed, is it possible to find component
on the market, and does exit free software?
Hi all,
At this frequency, SMt capacitor xseem vey critical, due
parasitc package effect, siz of component, pcb effect...
U can see on Murata web if they sale this type of capacitor (you can dowload S parameter file),
i know that for 402 size frequency are limited to 6Ghz,
maybe u need to use...
Hi ,
iif u measure the gain of all Rx path, u need
to use a RFsignal generator (with 50 ohm port),
set th gain of the receiver to the max gain,
then meaure the I ,Q level ( in Volt)on high impedance
and calculate the equivalent RMS I,Q level in dBm on a 50 ohm load
.
Hi IDK,
I have read your problem,
Before to destroy your mobile , check that the problem come from
the receiver part , it exist code (call GSM string) you enter that give you the receive signal from other cell in th network. As you said good mobile have a sensitivity aroud -108 dBm (-110 for...
Hi ,
I am actually trying to design a spectrum analyser,
is anybody knows if it s possible to use a computer sreen (insted of an oscilloscope) to sweep the Power vs frequency?
