Does AMPS co-exist with WCDMA? - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Per my understanding, due to AMPS signal co-existing with CDMA signal, there is Single Tone Desense (STD) spec for CDMA. I know that in WCDMA there are blockers spec for GSM signal. How about AMPS for WCDMA? I think that they could be operating in the same frequency. For example, CDMA cell band center frequency is 836.5MHz, and WCDMA band 5 center freqeuncy is 836.5MHz. Why AMPS signal will not bother WCMDA like CDMA? My only guess is that operators could make sure not to let AMPS co-exist with WCMDA.

Also I would like to know if any carrier uses AMPS as I doubt about it.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
