I am considering the use of a HMC549MS8G as a balun (instead of a transformer) on the RF port of the ADL5801.
- The reverse isolation of the amp will suppress the -30 dBm LO signal leaking out of the RF port a bit, which would be beneficial in my application.
- The little bit of low noise gain up front is just enough to still avoid saturation but be attractive for improving the noise figure
I am however operating in a 50 ohm system.
Are the complex S-parameters of the HMC549MS8G ports available (I would like to see it from 300 MHz- 1000 MHz), so that one can see how bad it will be or if some tuning can be done?
