REP005: Dual-band CDMA tuning front-end using inexpensive 85MHz IF SAW devices

This reference design (RD) is for a dual-band, triple-mode CDMA front-end IC tuned for use with IF SAW filters. The RD modifies the FM/cellular/PCS mixers to a common 85MHz IF. The design uses a low -noise amplifier (LNA) with mixer, the MAX2320, that is also useful for TDMA, GSM, and EDGE applications. Schematics and bill of materials are shown.

FreeEEG32: Affordable, stackable, open source, 32-channel EEG

FreeEEG32 is a stackable, open source, 32-channel, 24-bit, sigma-delta, simultaneous sampling board designed to meet the needs of scientists and brain hackers who require high-quality, affordable research-grade equipment. We have been developing this EEG for many years as we worked to create the ultimate open source solution to expensive proprietary EEG technology. FreeEEG32 combines four 8-channel AD7771 ADCs with ultra-low noise (<0.22 μV measured) sources and references, all driven by the powerful STM32H7 ARM Cortex-M7, while handling pre-processing. It's sensitive enough to handle high-quality EEG data collection and more.

900MHz full-duplex wireless transmitter reference design

This reference design covers the design of a transmitter inside a 900MHz full-duplex radio using the MAX2902 single-chip transmitter. The MAX2902 is designed for use in the 868MHz to 915MHz frequency band, and complies with FCC CFR47 part 15.247 902MHz to 928MHz ISM band specifications. The reference design is capable of delivering more than +19dBm with V _CC = 2.9V and I _CC = 170mA, and +20dBm with V _CC = 3.3V and I _CC = 190mA, while meeting 14dB of CNR (1.22Mbps BPSK) at 10:1 VSWR (all angles).
