The MAX2039 evaluation kit (EV kit) simplifies the evaluation of the MAX2039 UMTS, DCS, and PCS base-station up/downconversion mixer. It is fully assembled and tested at the factory. Standard 50 SMA connectors are included on the EV kit's input and output ports to allow quick and easy evaluation on the test bench. This document provides a list of test equipment required to evaluate the device, a straight-forward test procedure to verify functionality, a description of the EV kit circuit, the circuit schematic, a bill of materials (BOM) for the kit, and artwork for each layer of the PC board.
