MAXIM MAX2745 handbook
Update: 28 September, 2023
The MAX2745 is a complete single-chip global positioning system (GPS) RF front-end downconverter that incorporates many innovative and leading-edge RF CMOS design techniques. It is a high-performance device with low power consumption, eliminating the need for costly SAW and bulky discrete IF filters. The MAX2745 includes a fully integrated low-noise amplifier (LNA) and mixer, IF section, digital sampler, and local oscillator synthesizer. It also provides a voltage supply for an external LNA and features a voltage booster that can extend the power-supply voltage to as low as 1.6V. The MAX2745 supports both 32MHz 3rd overtone crystal designs and 16MHz fundamental frequency crystal designs, as well as TCXO implementation. Additionally, it incorporates an on-chip temperature sensor and crystal oscillator with trimmed capacitors for accurate frequency and cost savings. The MAX2745 is available in a space-saving 48-pin TQFP package and is specified for the extended (-40°C to +85°C) temperature range. The device consumes as low as 41mW power at 2.4V.
