Washington, D.C. 2ooo6 PRICE: Please refer to the current Catalog of EIA consequently portions of the specification may not be applicable to unpackaged and unmounted chips. The intent of this specification is to serve a
9、s a guideline for transistor manufacturers and users (purchasers) to use in the development of their own specifications for power GaAs FETs for applications requiring high reliability. The specific applications and device designs will define the values for parameters left undefined in this specifica
