I did this a long time ago with an NE602, in a receiver with audio-derived AGC. Then C1, C2 and L form the tuned tank circuit with the condition for oscillations being: X C1 + X C2 = X L, the same as for the Hartley oscillator circuit. It still needs some work but I am certain there are many NE602 receivers out there that can be modified to test this out. The SA602 was designed for the second conversion stage in early cellphones - NOT for an HF front-end. ) has been around for about six years. Thus, a 9-IvlHz input and a 2-MHz LO yield outputs of 7 and 11 MHz. Grab with glfer or baudline.

Posted on Feb 7, 2014. Floyd View attachment 357445. The NE602 is a decent mixer for homebrew projects but due to its well-known shortcomings, namely the mediocre intercept point (the noise figure is decent and the 500MHz upper frequency limit is sufficient for most projects), it is not a worthy candidate for replication with discrete components. Sonuca ulaşabilmek için piyasadaki ürünleri de tek tek incelemek mantıklı gelmedi. The guaranteed parameters of the SA602A make this device particularly well suited for cellular radio applications. up to 7 MHz.
