We plan to use the LTC6948-3 with a 5GHz output, using a balun to produce a single-ended output.
I have a few questions regarding this:
- The HHM1570B1 is out of stock and we have decided to go for the HHM1595A1 which has a wider band at the price of a ~-20dB insertion loss. Any restriction on this?
- In Figure 18 (see below), there is no indication on the impedance of the lines connecting RF+/- to the balanced inputs of the balun. Which impedance do you recommend? Or should be use the single ended matching circuit from Figure 16 on both branch?
Thank you in advance for your support!
