Can HMC1033 be used with Mixer LT5512

This should work just fine.  I would start with a single ended interface due to the small LO requirements of the LT5512.  

Refer to figure 20 of the HMC1033 datasheet for the unused single ended port.  Refer to Figure 6 of the LT5512 datasheet (the 100 ohm external makes is in parallel with the  2 parallel 200 ohms resistors internal to the LT5512 LO input - making for a 50 ohm termination).

Thanks for help.

I don't understand this phrase very well : due to the small LO requirements of the LT5512. I didn't find any infomation about these requirements related in the datasheet...

If I use HMC1033 in 50 ohm single-ended, what should I place for the unused port (for example OUT_N) ? Is a capacitor enough for this before connecting to ground ? Which value should I take ?

I perfer using HMC1033 in differential mode to drive LTC5512 for improving CMRR purpose (LO input freq. about 200MHz). Do you have some suggestions for differential mode ?

BR,

LT5512 datasheet Page 2 has the LO input power specifications.

For the unused port use a cap and 50ohm resistor as shown in Figure 20.  Refer to the eval board schematic for the value of the capacitor.

You can use a differential signal just make sure you do not exceed the LT5512 page 2 LO input specifications.  

Thanks for explication.

In datasheet of LT5512, page 8, I would like to know why the calculation of L1 and L2 doesn't take account the value 5.2 Ohm reactance (given by the input diff impedance). Or am I wrong ?

Thanks in advances
