The file is .PCB , so which program you used ? can u please upload image version of your ct ( .jpg or .bmp) ?
I'm sorry!
It's in Protel 99se format!
I will soon upload some pictures of the circuit !
The signal propagation path: RF --- RF fILTER --- MIXER --- IF AMP --- IF VGA
top layer: red (for RF signal)
layer 2 :grown(for a complete ground plane)
layer 3 :green(for a VCC plane with two patches of ground plane)
bottom layer : blue(for ground plane)
The hight between top layer annd layer2 is 0.23mm。
The RF input power is about -113dBm
The LO power is about +15dBm
RF gain (U1 U2 U3 U4) is about 30dB.
Insertion loss of RF Filter is 3dB
Conversion Loss of MIXER is about 7dB
Gain of IF AMP is 20dB
Maxium gain of VGA is about 33dB.
