MAX2165 DMB-TH USB Dongle Reference Design

This compact USB dongle design combines a MAX2165 direct-conversion tuner and a DMB-TH demodulator. The design converts a UHF signal (470MHz to 858MHz) to a MPEG-2 transport stream. Then the USB interface enables video viewing on a laptop or desktop computer.

REP023: Upconverter from 350MHz to 3.5GHz with 9dB gain and 1.3dBm IIP3

This reference design (RD) shows how a downconverter with selectable LO doubler can be used as an upconverter. The RD achieves 9dB gain and 1.3dBm IIP3. The MAX2683 low-power downconverter designed to operate in the receive path of 3.5GHz wireless data transceivers is featured. Schematics, test setup, BOM, and performance results are shown.

MAXREFDES70#: High Accuracy, Long Battery Life Heat/Flow Meter

The MAXREFDES70# reference design is a high-precision, low-cost, low-power consumption, battery-powered heat/flow meter featuring the MAX35101 ultrasonic time-to-digital (TDC) converter with analog front-end (AFE). The reference design provides a high-performance flow/heat meter design platform that works as a foundation for many specific meter applications. The system utilizes the ultrasonic time-of-flight (TOF) measurement principle. A 3.6V, 4.0Ah, size A lithium -thionyl chloride battery powers the system and can last up to 20 years for typical use. Test results, hardware files, and firmware source code provide complete documentation for the design. The complete meter is also available for purchase.

Wearable device power supply reference design for wireless charging using bq51003 and bq25120

Wearable devices require advanced power management to keep batteries running for extended periods of time while enabling always-on functionality. In addition, the device needs to use small rechargeable batteries and support a small form factor design. This application note shows how to implement a scalable power management solution for wearable devices that can be customized for activity monitors or smart watches. This design features a Li-ion battery charger and low quiescent current (Iq) DC/DC buck and boost converters for PMOLED displays, a boost converter for heart rate monitors (HRM) and a second Configured with low Iq DC/DC buck, it provides wireless charging input and highly configurable battery management solution.

MAXREFDESGPS_B: How to add GPS to your product without draining your battery

The GPS reference design is an evaluation kit designed to demonstrate the essential features of an ultra-low power GPS (global positioning system) receiver, as well as serving as a reference design to illustrate how to implement such a receiver rapidly. The reference design uses the MAX2769C L1-band GNSS RF front end IC (RFIC) from Maxim Integrated, and the ultra-low power GPS baseband processing firmware provided by Baseband Technologies Inc. (BTI) that runs on a MAX32632 microcontroller unit (MCU).
