Block down conversion:

Noise ﬁ gure measurements up to 110 GHz

Agilent offers the K-Series block downconverters which extend the upper

frequency limit of the N8975A or N9020A-526 from 26.5 GHz up to 110 GHz. The

downconverter uses an internal LO to down convert the input signal to an IF

that is within the measurement range. The K-Series is offered in 13.5 GHz bands.

For example, a customer that would like to do noise ﬁ gure measurements to

52 GHz would order K40, K50, and K63 in order to bridge from the 26.5 GHz end

frequency of their instrument to 52 GHz.
