ADC32RF80: ADC input reference circuit

Part Number: ADC32RF80

Hello,

1. Do we have a reference circuit by using NCS1-422+ for ADC analog input?

If yes, please provide it. If no, it would be helpful if the recommendation circuit is provided.

2. We are seeing TCW1-3901+. Which NCS1-422+ or TCW1-3901+ is recommended?

The target RF frequency is 3400 to 3600MHz.

Best regards,

Watanabe-san:

We have not used the NCS1-422+ balun before but looking at the datasheet it appears to be a good choice for 3.5 GHz band operation. It looks better than the TCW1 related to the pin-out and phase balance. Between the two I recommend the NCS1 device.

Hello Hopper-san,

I understood there is no reference circuit by using NCS1-422+. Do you think possible if we can make the reference circuit by using NCS1-422+?

Best regards,
