High-Throughput, Multi-Function, On-Wafer Test System

analyzing and solving numerous hardware and software test issues, and it requires a thorough knowledge of the entire test environment. The most effective way to address the variety of issues is to create a partnership between several companies (hardware and software vendors and end users). In this spirit, ITT, HP, IMS and Cascade are working together to create an on-wafer RF test environment which addresses high throughput, low cost military test needs. HP is chartered with developing the test system hardware, Cascaded is chartered with developing the test executive software (test plan editor, probe plan editor, display utilities, etc.), IMS is chartered with developing the software measurement modules (S Parameters, NF, PldB, etc.), and ITT will integrate and evaluate the entire system. The objective of our efforts is to create a software reconfigureable, high throughput, on-wafer test system that can characterize all MMICs (including power amplifier ICs) at the lowest possible per unit test cost.
