Abstract
An observation signal generation device includes a local signal generator, a first mixer which mixes an RF signal to be observed with the local signal and outputs a first IF signal, a second mixer which mixes the RF signal and the local signal and outputs a second IF signal, an first IF filter which includes a first intermediate frequency obtained by subtracting a frequency of the local signal from a first frequency of the RF signal in a passband, includes a second intermediate frequency obtained by subtracting a frequency of the RF signal from the frequency of the local signal in an attenuation band, and filters the first IF signal to generate a first observation signal, and an second IF filter includes the first intermediate frequency in the attenuation band and the second intermediate frequency in the passband, and filters the second IF signal to generate a second observation signal.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
