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 **broken link removed**
.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.
