really thanks that's very helpful
i'm making jamming locator device it's basic idea depends on receiving signal from array antenna and perform some operation on the signal
so i need an antenna first to accept the signal then pass to rf receiver consists of mixer,oscillator and amplifier then pass the signal to ADC then get the IQ
then from the IQ output i will perform my circuit ,,, so i need an RF receiver that doesn't make modulation just i want the IQ output so please answer me
and about the circuit you discussed above using cc2500 here we get I Q ,, or an low freq signal or an digital signal .... if it's possible can you show me shematic or help me with any link of what your talking about

CC2500 features a low-IF receiver. The
received RF signal is amplified by the lownoise
amplifier (LNA) and down-converted in
quadrature (I and Q) to the intermediate
frequency (IF). At IF, the I/Q signals are
digitised by the ADCs. Automatic gain control
(AGC), fine channel filtering, demodulation
bit/packet synchronization is performed
digitally.
so if it's possible i want to get the output of ADC directly not pass to the modulator part or any other following blocks
