Part Number: ADC12DJ5200RF
Other Parts Discussed in Thread: TRF1208

Hello,

My customer is considering designing a Zero-IF application using the ADC12DJ5200RF.

Are there any problems implementing Zero-IF applications with ADC12DJ5200RF?

If you have reference design data for this configuration, please provide it.

Thank you.

Hello Eric,

Thanks for your reply.

The customer is looking for reference on Balun design to receive Zero-IF signals with ADC12DJ5200RF.

Could you provide design data related to this?

Best Regards,

Hello JH,

if you want to see a balun design then you can look at the evm available on ti.com. The only thing to note is this balun I chosen to for a specific bw it is roughly 100s kHz - 9 GHz. So depending on your customers bw requirements they may want to choose something different.

best,

Eric

Hello Eric,

I would like to apply the circuit diagram in Figure 8.5 in Datasheet for DC-coupled signal.

The EVM does not have a circuit like Figure 8.

I would like to request the circuit diagram in Figure 8.

Best Regards.

Hello Jongroh,

I have checked and the closet thing we have to offer as far as a schematic goes is the TRF1208 + ADC12DJ5200RF EVM design available on TI.com.

Best,

Eric
