mixer circuit design

Hi Bro,

I am currently taking a RF module and is stuck with designing a Mixer circuit.
The RF input frequency will be 105 Mhz and LO frequency is 110Mhz. I need to get 5 Mhz IF frequency. I am unsure how to start tackling this design. Any bros can advise me? I really appreciate any advices. Thanks

Regards

Your best bet is a diode ring mixer which can be purchased as a module. Use LC diplexers on all three ports.
