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.

UsbSafe²: an open, programmable dongle for protecting USB devices from USB hosts and chargers

Always stay secure and protect your private data and gadgets when connected via USB. USB connections transfer information and power. UsbSafe² is a device that protects USB-connected hardware from excessive voltage, current, and unauthorized data access. Unfortunately, the practice of “juicing” (accessing data from devices connected to public charging stations) has become very common. UsbSafe² offers a unique combination of anti-juicing mode and fail-power protection. With UsbSafe², you'll feel safer no matter where you are or what you plug in, your valuable gadgets are protected and secured!
