The MAX19793 evaluation kit (EV kit) simplifies the evaluation of the MAX19793. The MAX19793 dual general- purpose analog voltage variable attenuator (VVA) is designed to interface with 50Ω systems operating in the 1500MHz to 6000MHz frequency range.
The MAX19793 is a monolithic VVA IC designed for broadband system applications, including wireless infrastructure digital and spread-spectrum communication systems WCDMA/LTE, TD-SCDMA/TD-LTE, WiMAX®, cdma2000®, GSM/EDGE, and MMDS base stations VSAT/satellite modems. The MAX19793 evaluation kit hosts a microcontroller (MCU) that uses a serial peripheral interface to configure internal registers and modes. Graphical User Interface (GUI) software running on a computer makes it simple to program registers and control the device operation. The evaluation kit is fully assembled and tested at the factory.
This document provides a component list, a list of equipment required to evaluate the device, a straightforward test procedure to verify functionality, a description of the EV kit circuit, the circuit schematic, and artwork for each layer of the printed circuit board (PCB).
