Design Considerations for >10 GHz operation
While the NB7L14M is specified to operate at 10 GHz,
this evaluation board is designed to support operating
frequencies up to 20 GHz.
The following considerations played a key role to ensure
this evaluation board achieves high
−
end microwave
performance:
•
Optimal SMA connector launch
•
Minimal insertion loss and signal dispersion
•
Accurate Transmission line matching (50 ohms)
•
Distributed effects while bypassing and noise filtering
