The VectorStar ME7838 Series broadband VNA offers the widest available single frequency sweep from 70 kHz to 110, (ME7838AX to 125), (ME7838EX to 125), to 145 GHz, and to 220 GHz with mmWave bands to 1.1 THz. 

• The ME7838AX or ME7838EX version can easily be upgraded to 145 GHz and to 220 GHz
• All versions may be configured to include banded millimeter-wave modules up to 1.1 THz
• Industry-best calibration and measurement stability: 0.1 dB vs 0.6 dB over 24 hrs.
• All versions support the 3744x-Rx receiver for noise figure measurements, including the ability to characterize differential noise figure, to 125 GHz
• Compact, lightweight mmWave modules (0.6 lb vs 7+ lbs and 1/50 the volume) offer low cost installation on smaller probe stations.

• Calibration-grade metrology standards
• Used for VNA calibration and/or calibration validation

A precision fixed termination (or load) consists of an immovable, (fixed) termination which, when mated to the end of a trans-mission line or cable, absorbs nearly all of the signal energy traveling toward it. An ideal “matched” condition exists when a termination with an impedance value of Z0, is connected to the end of a transmission line or cable that also has a characteristic impedance of Z0. Such an ideal “matched” condition (one with no mismatch between the termination and its mated line or cable) is critical if a voltage standing wave ratio (VSWR) of 1.0:1 is to be achieved in a system with a 50 or 75 ohm impedance value. Simply put, the more closely the 1.0:1 ratio is approached, the more accurate the measurements that can be made from a system.

• Complete bias circuits
• Requires no external components
• Extremely flat output power versus frequency characteristics

The NC500 (through-hole) and NC500SM (surface mount) Series noise modules are an economical solution for built-in test requirements. They contain complete bias circuits and require no external components. Some models contain additional gain stages for high power ENR output (51 dB). The surface mount package is suitable for mounting on micro strip. The modules have extremely flat output power versus frequency characteristics that are insensitive to temperature and voltage variations.

Fixed flush and fixed offset short circuit terminations (shorts) are used to establish reference planes in transmission systems and as key elements in the calibration of vector network analyzers (VNAs). Offset shorts can be used for banded calibrations of VNA. Those with the longest offset are often used to evaluate the calibration effectiveness of a VNA by measuring the effective source match after calibration.

Junkosha’s new mmWave VNA Test Cable Assembly exhibits excellent phase (within +/- 4.5˚ at 50 GHz), and amplitude (within +/- 0.08 dB at 50 GHz) stability in flexure alongside strong phase stability in temperature through its 50 GHz bandwidth, available with NMD connector.

The assembly also displays impressive performance durability, surpassing 40,000 tick tock cycles during testing. The cable is bent 180˚ on a 2.25” radius mandrel with ease, demonstrating superior flexibility and no spring back. A ruggedized port side NMD connector is also available to ensure reliable connections to the VNA.
