Gsm radiation detector

Hi,

I am working on a project on instrumentation that involves the design of an RF gadget to read the ambient-RF-signal level of signals emitted from cell phones. I am making a follow up on literature of similar device. A publication by Vladimir Dvorkin available at http://www.edn.com/file/12352-Figure_1.pdf
is my good guide. He uses TDFU2A-2450T-10A to 'sniff' out 2.4-to 2.5- GHz signals. Kindly advice me on which part (filter) I could use to detect
out GSM RF signals. I will be grateful.

Thanks.

Dominic.

That link shows "page not found" error, check link.

Link fixed.

Check the link for filters for GSM 900MHz, GSM 1800MHz, GSM 850MHz, or GSM 1900MHz, depend what band you are looking for.
