OML VNA Modules are Universal Compatibility with 20 GHz Network Analyzers

OML announces a direct connect configuration that supports millimeter wave S-parameter measurements using the ZVA series network analyzer from Rohde & Schwarz. This entry-level configuration offers engineers the versatility to connect VxxVNA2 series modules directly to the front panel of a four-port dual-source vector network analyzer. As a prerequisite, this entry-level millimeter wave system configuration relies on the R&S ZVA-24 (or higher frequency model). Contact OML for more order configuration and system operation details.

As this announcement demonstrates, engineers can use new (or existing) VxxVNA2 series modules with their preferred network analyzer model. In general, the direct-connect configuration supports fully-reversing two-port S-parameter measurements consisting of S11, S21, S12 and S22. More economical subsets of these S-parameters are also available along with options for power control and amplification to overcome long cable runs between modules and network analyzer.

Available in waveguide bands from 50 GHz to 0.5 THz, the VxxVNA2 series modules support a variety of popular measurement scenarios: test fixture, on-wafer, material, and antenna applications. The output waveguide flange is compatible with MIL-DTL-3922/67D. These VNA modules from OML are available in eco-friendly RoHS compliant variants for WR-10, WR-05, WR-03 and WR-02.2. OML currently offers the industry’s best delivery for popular models.
