Low-Noise 12 GHz Microwave Fractional-N Phase-Locked Loop (PLL) Using Active Loop Filter and RF Prescaler
Precision electronic scale design using 24-bit Σ-Δ ADC AD7791 and external zero-drift amplifier ADA4528-1
This reference design (RD) is for a dual-band, dual-mode CDMA front-end that uses a CDMA LNA/mixer, the MAX2323. The RD retunes the FM analog and the cellular/PCS digital mixers to 210MHz IF. This CDMA low-noise amplifier is also useful for TDMA, GSM, EDGE, and WCDMA applications. Schematics and bill of materials are shown.
The WiBro™ reference design is a complete RF front-end solution designed to meet requirements for the WiBro 2.3GHz to 2.4GHz mobile WMAN (Wireless Metropolitan Area Network) standard. This reference design uses the MAX2837 direct-conversion transceiver and demonstrates a complete WiBro single-band RF-to-baseband solution. It serves as a platform for designs in multiple form factors such as CardBus, miniPCI, and custom CPE modules. The design can be easily adapted for WiBro-only 3.3V laptop applications, or WiBro- only 5.0V CPE applications.
12-bit, 300 kSPS, single supply, fully isolated data acquisition system for 4-20 mA input
The 1/8 brick power module in this reference design is designed based on the 1/8 brick power supply standard defined by the Distributed Power Open Standards Alliance (DOSA). This power module uses an Analog Devices ADP1051 to control the energy conversion from input to output.
Crest factor, peak and rms RF power measurement circuit optimized for high speed, low power and single 3.3 V supply
This reference design (RD) shows how a dual-band, dual-mode CDMA front-end IC can drive an IRF3100 IF demodulator. The RD features the MAX2323 CDMA low-noise amplifier which is also useful for TDMA, GSM, EDGE, and WCDMA applications. Schematics, the bill of materials (BOM), and performance results are shown.
