and amplitude balance enable high performance intermediate
frequency or direct radio frequency modulation for commu-
nication systems.
The

from 450 MHz to 3.5 GHz. These features, coupled with a broad-
band output return loss of ≤−12 dB, make the
suited for broadband zero IF or low IF-to-RF applications,
