RF mixer design for cognitive radio

Hi. I need to design mixer for cognitive radio. im new for IC designing. So anyone can give me right direction meanwhile if any doubt i can clarify. I have to design using Cadence software. beside that anyone can can give good explanation abt conversion loss. I roughly understood but i not understand the 7dBm of LO and the level.

thank you

Hello,

For a mixer the OL's level is specified in order to produce the intermodulation products.
The manufacturer produce differents mixers with differents levels. The level to choice depend on the level produce by your PLL or synthetizer (DDS) that produce your LO.
I suggest you to have a look at the Minicircuit documentation that is very understandable at this link :
http://217.34.103.131/app/AN00-010.pdf for the mixer or
http://217.34.103.131/applications/a...ons_notes.html for the all applications notes of minicircuit.

Specially, they offer an application note that deal with "How to chose a Mixer".

Good work.

Thank you. I try to go through the link. If any doubt i catch u later. Seem it good link.
