Agilent Technologies, Inc. 70910A Switchable Bypass Filter Around YIG Tuned Filter
Feature:
Minimum Frequency: 100Hz
Maximum Frequency: 26.5GHz
The HP 70910A RF section provides coverage from 100 Hz to 26.5 GHz. This RF section is used in the HP 71209A Opt 001 spectrum analyzer and the HP 71910A surveillance receiver. 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). The HP 70910A adds the switchable bypass path around the yig-tuned filter (YTF) for making very sensitive measurements when extraneous signals are not a problem. Also, the HP 70910A ensures that the minimum bandwidth through the YTF is greater than 36 MHz and the minimum bandwidth through the low-band path is greater than 45 MHz. For millimeter measurements, this RF section includes the extra switching and signals necessary to connect external mixers, including HP 11974 series preselected mixers. A switched LO is routed to the front panel for connec
