wrote: Hi Don, Thank you for that information and offer. I have that issue of Electronics Now. The article starts on page 47. This looks like what I want!! Brad By the way, I found some notes that the SA612A is a later and better pin-for-pin replacement for the 602. Have fun.

The output will be in the UHF band. Note: This will be a low level signal output. I found one semi-conductor, UPC8163TB, that meets the specs on the web, but it is too small (about the size of a grain of rice). Although I am an experienced electronics tech, I don't have the special equipment to mount this "speck" IC on a circuit board. I searched sites such as www.nxp.com (Philips), Mouser, Digi-Key for a larger semiconductor with similar specs, but I didn't find one. Do you have any information about another RF frequency upconverter that is physically larger? Thanks in advance, Brad Before you type your password, credit card number, etc., be sure there is no active keystroke logger (spyware) in your PC. The NE602 (Signetics) or SA602 (Philips) may be a good choice. The Philips Application Notes, AN1981, is helpful. This IC has been around for at least 10 years so you may find an update of it available. I have a MS WORD copy of a Feb. 97, Electronics Now Article that discusses it at some length. You can email me for it if you decide to try the IC, which by the way, has an on-chip oscillator, which makes it's use quite simple. If needed, I can convert it to PDF. |
