NRC Herzberg Astronomy and Astrophysics (HAA) requires extended measurement capabilities in the millimetre-wave frequency range to support ongoing research in characterizing front-end components for low-noise receivers in radio astronomy. Existing Vector Network Analyzers (VNAs) at NRC HAA are currently limited to a maximum operational frequency of 116 GHz. To increase its measurement capability, NRC HAA intends to acquire frequency extender modules covering the 110–170 GHz band. These extenders must integrate with either of HAA's existing analysers (Keysight PNA N5227B and Rohde & Schwarz ZNA67), providing high dynamic range and stable two-port measurements.
