170 GHz / 220 GHz Broadband Vector Network Analysis Solution

New 170 GHz / 220 GHz Broadband Vector Network Analysis

Enabling Insights into Broadband device performance

Keysight together with world-leading millimeter-wave solution partners offer a single-sweep VNA on-wafer solution operating from 900 Hz / 10 MHz – 170 / 220 GHz. This innovative solution has the best dynamic range, highest output power, and greatest stability over time in the industry. Designers can use these advantages to efficiently characterize on-wafer devices and circuits, enabling the creation of highly accurate PDK models that will shorten the design and verification cycle and allow faster deployment of devices for the emerging 5G and 6G MMICs. The solution comprises Keysight’s N5291A industry-leading 125 GHz broadband VNA together with VDI’s specially designed sub-THz frequency extenders and FormFactor T-Wave GSG Dual band probes with 50-to-100-um-pitch 1. This fully integrated solution using FormFactor’s WinCal calibration software and standards enables accurate calibration to achieve the best measurement performance in the market. All of this has been carefully integrated onto FormFactor’s industry leading Probing Systems insure ease of use.

Since it’s based on the N5291A and uses VDI’s sub-THz modules, it makes very simple to upgrade to this broadband VNA configuration.

Solution architecture

As mentioned above, the solution leverages Keysight N5291A broadband VNA, and it includes Keysight’s N52xxB PNA network analyzer, N5292A 4-port test set controller and N5295AX frequency extenders. In addition, it uses VDI’s 110 GHz to 170 GHz or 130 GHz to 220 GHz frequency extender module. The onwafer device characterization is realized by the FormFactor T-Wave Dual Band Probe with its replaceable integrated probe chip technology.

Excellent Measurement performance

This 170 GHz / 220 GHz broadband VNA solutions provide great dynamic range and maximum allowable output power, broadband leveled power flatness. (The performance data for the 220 GHz configuration is Supplemental Performance Data (SPD). The performance data for the 170 GHz VNA configuration is estimated preliminary data.)

Highest output power

This solution achieves the maximum allowable output power of +5 dBm at the probe tip at 220 GHz and help you to evaluate your DUT like an amplifier at a high-power input.
