the max2769 evaluation kit (ev kit) simplifies evaluation of the max2769 universal gps receiver. it enables testing of the device performance and requires no additional support circuitry. standard 50sma connectors are included on the ev kit for the inputs and
outputs to allow for quick and easy evaluation on the test bench. 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).
max2769評估板主要特性：
♦ easy evaluation of the max2769 ic
♦ +2.7v to +3.3v single-supply operation
♦ 50sma connector on the rf ports and for the baseband outputs
♦ all critical peripheral components included
♦ parallel port for 3-wire interfacing
♦ pc control software available upon request
