Agilent / HP / Keysight 70909A
70909A RF Section, 100 Hz to 26.5 GHz
This RF section is used in the Agilent 71209A spectrum analyzer.
Diode pair mixing provides lower conversion loss, allowing the spectrum analyzer to have sensitivities that compete with fundamentally mixed designs.
The sensitivity is also improved by the use of a built-in preamplifier before the first mixer (in the microwave path).
For millimeter measurements, this RF section includes the extra switching and signals necessary to connect external mixers, including Agilent 11974 series preselected mixers.
