I have one wireless-audio project in the idea that RF(868MHz) directly downconvert to IF 10.7MHz.

Could anybody give some suggestions to this Mixer or downconverter. no matter it consist of transistor circuit or RF IC

Frequency (RF): 800 - 1000 MHZ
Frequency (IF): 10.7 MHz
Noise Figure: 15 dB
Gain: 8 dB Min.


Thank you first
