Today’s evolution in high-speed
semiconductor technologies such as
RF-CMOS, GaN, and SiGe are continu-
ing to push the application frequency
limit up higher and higher in micro-
wave and millimeter-wave ranges. As
the requirements of new commercial
market applications such as automo-
tive radars, UWB communication links
and wireless LAN/PAN, as well as
traditional aerospace and defense ap-
plications become more rigid, charac-
terizing phase noise of a signal source
is getting more important than ever.
In addition, a simple and cost-effec-
tive method to evaluate phase noise
when testing as many parameters as
possible in microwave signal sources,
is expected.
The Keysight Technologies, Inc.
E5052B Signal Source Analyzer (SSA),
along with the E5053A Microwave
Downconverter, has an extended

frequency range up to 26.5 GHz.
Shown in Figure 1, all six fundamental
functions available in the E5052B (10
MHz to 7 GHz) are now usable up to
26.5 GHz with the E5053A. The phase
noise measurement capability can be
extended to 110 GHz with external
harmonic mixers supplied by Keysight
or third parties.
