does some one have a tested circuit for it
i have a problem in useing its built in oscillator
i am trying to build a dc receiver (direct conversion receiver)
:D
 

sa602

i have done quite a number of designs with the NE602 and it's replacement SA612. what is the problem you are hiving with the oscillator?

sa602 direct conversion

sorry for being late in replying
i connected it like this

the sa602 share supply with other ic from the same 5v regulator
why does this circuit doesn't work?
i use it as direct conversion receiver
the sa602 only act as amp!!!!!!!!!!!!!!

:cry:
 

sa 602 ic

It happened many times that circuit dont work at first time.
Have you checked if oscillator works?
Have you connected circuit properly?
Is your test method right?

you always see the datasheet and applications. start your design based on the circuits there.
