Datasheet

Overview

The VectorStar ME7838D is a broadband vector network analyzer system that provides single-sweep coverage from 70 kHz to 145 GHz and is operational from 40 kHz to 145 GHz. It uses the Anritsu-developed 0.8 mm coaxial connector, so frequencies up to 145 GHz propagate in a coaxial line without waveguide flange connections. Devices can be characterized from near-DC through the W band and F band in one sweep, without concatenating multiple systems.

The broadband system consists of an MS4647B VectorStar VNA (70 kHz to 70 GHz, with Option 7, Option 70 and Option 80/81), a 3739C Broadband Millimeter-Wave Test Set with interface cables, and two MA25300A millimeter-wave modules. The modules use Anritsu nonlinear transmission line (NLTL) technology. They are small and light enough to position precisely on a wafer probe station, and they level power in real time without calibration software correction tables.

Waveguide bands

A millimeter-wave configuration provides waveguide output from 50 GHz to 1.1 THz. It can extend the broadband system or run as a waveguide-only system. Supported waveguide setups include adapting the MA25300A module with waveguide adapters, the 3744A-EE and 3744A-EW extended E- and W-band modules, and VDI frequency extension modules.

Measurement capabilities

The ME7838D supports the 3744A-Rx 30 GHz to 125 GHz receiver for noise figure measurements up to 125 GHz. Option 48 adds differential noise figure. Other options include time domain, Universal Fixture Extraction, DifferentialView, IMDView, PulseView, eye diagram and spectrum analysis. SC8215 and SC7287 Kelvin bias tees support tri-axial bias connections for on-wafer device biasing up to 145 GHz.
