Hello,
is any one can guide me to built a costas receiver. At the input of a mixer the LO and RF signal creates an IF signal. This IF is the frequency difference of LO and RF irrespective of their position of frequency spectrum, i mean IF=LO-RF or IF=RF-LO. I need to track this IF signal at the...
as 74hc393 is a binary ripple counter, this means my input frequency has to be binary. But my signal will be an analog signal. in that case what kind of frequency devider will be suitable?
i have a RF-LO specification
-50dBc/Hz @ 1KHz
-70dBc/Hz @ 10KHz
-90dBc/Hz @ 100KHz
-110dBc/Hz @1MHz
now i like to compare this with an optically generated LO whose PSD is
S(f)=(2*A/pi)*(w/(4*(f-f0)^2+w^2))
where, A=is the amplitude;
f0=carrier frequency;
w=LO linewidth;
i...
Hello, i have a laser phase noise data as
-50dBc/Hz @ 1KHz
-70dBc/Hz @ 10KHz
90dBc/Hz @ 100KHz
now from these data how can i draw a lase power spectrum(dbm)
thanks

hello,
i need to determine the LO power in an LNB. i have the following values:
received power=-117 dBW; poise power -128dBw; Noise figure of LNB=1dB; LNA gain=50dB.
How can i use these info to relate the LO power.
thanks in advance
Reza
