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 typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

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. Note: The RF Cafe Forums were reconstituted in April 2021!

Hi everyone!

I have a small question, when comparing two transceiver chips, I read something about Adjacent channel power (ACP). Can anyone tell me what Adjacent channel power means?

And for a good performance, is it beter to have a high or low ACP??

Tranks!

Enno.

Greetings Mr. Enno:

As the name suggests, adjacent channel power is the amount of power a transmitter allows to "bleed" into the channel just above and below it. Lower ACPs are always better, because it means you are not as likely to interfere with a co-existing system trying to operate in the same frequency space.

Here is an illustration that uses co-existence of Zigbee with WiFi. Bluetooth could also be added to the picture because like ZigBee, it uses a frequency-hopping spread spectrum scheme.
