The low power VxxVNA2-LP series has been added to OML’s VNA Frequency Extension family. Maintaining the current VNA’s capability to expand existing VNA systems to conduct millimeter wave S-parameters measurements, the new low power VNA series now offers a maximum output power of 0 dBm. The low power module also provides the option to test low power active devices.
With its maximum output power of 0 dBm the low power series still offers the same top-quality specifications as the original VNA. Featuring OML’s high performance coupler and millimeter wave isolator, this unit is stated to provide superior results of a typical raw directivity of 37 dB and typical dynamic range of 110 dB.
This module can be utilized to display two port S-parameter measurements (S11, S21, S12 and S22) on the VNA. Tailored to fit customer needs, modules can be set up with four different architectures: 1-port, scalar 2-port, 1-path/2-port and fully reversing 2-port. Measuring 12.6" × 4.3" × 2.7" (320 × 109 × 69 mm) the sleek design can also be used with probe stations.
Manual Adjustable Attenuator
Options for this series still include a manual adjustable attenuator (0 to 25 dB) to the RF path; addition of an amplifier (15 dB gain) in LO path for drive input of -5 dBm; and intermodulation distortion measurement (IMD). The low power
VxxVNA2-LP series is currently available in waveguide bands from 50 to 110 GHz.
