REP021: Front-end devices for 2.5GHz Globalstar and IS-95

This reference design (RD) is for a dual-band CDMA front-end IC that uses a PCS-band signal path for 2.5GHz LEO satellite channel and a cellular-band signal path for GlobalStar IS-95 CDMA applications. The MAX2323 LNA plus mixer for dual-band CDMA handsets is featured.

Schematic PCB

High performance 1-Wire network driver

This document describes a microcontroller-based 1-Wire® master interface for reliable operation of small, medium, and large 1-Wire networks. This is accomplished using careful impedance matching, intelligent (software-controlled) active pullup, and slew-rate control. Software flow charts are included to assist the user in generating the correct 1-Wire timing for reset pulse, presence detect, write one, write zero, and read time slots using any suitable microcontroller. Scope traces illustrate the timing performance of the driver as well as transmission line effects as they appear with long cables.

Designing robust, fault-tolerant motion control feedback systems

This article reviews basic servo systems and development of the fault-tolerant feedback systems for servo systems. Controller receiver circuit design, proper PC-board receiver circuit layout, and the encoder's signal cable and termination are discussed. Additionally, various types of industrial feedback encoders are presented, along with the various types of faults that can develop in a servo feedback system.

MAX2160 ISDB-T Reference Design

This reference design for the MAX2160 tuner plus demodulator IC demonstrates a compact daughter-board solution for the ISDB-T standard (single-segment). This design converts UHF band signals (470MHz to 770MHz) to a MPEG-2 transport stream. The solution is intended for portable applications, such as cell-phone TVs and PDAs.

Choosing the Right 1-Wire Host for Your Embedded Application

This application note presents four categories of 1-Wire master circuits for embedded applications and discusses their capabilities and requirements in relation to available (ie, unused) system resources. The schematics shown here apply to short networks that do not extend beyond the radius of 1 meter and are populated with a small number of 1-Wire slaves. Instructions and a decision worksheet are included to identify the most cost-effective 1-Wire master for the application. The reader should be familiar with the basics of 1-Wire communication and microcontrollers.

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.

MAX3541 DVB-T/PAL Tuner

The MAX3541 is an integrated, single-conversion terrestrial tuner IC for DVB-T and PAL. The device is designed to convert input signals in the VHF-Low, VHF-High, and UHF bands to an IF frequency of 36MHz. The MAX3541 is designed for television, analog/digital terrestrial receiver, and digital set-top box applications.

802.11b/g RF front-end module reference design using the MAX2830

This module uses the highly integrated MAX2830 RF transceiver. It is a complete RF front-end solution that meets the WLAN IEEE^SM 802.11b/g standard. The transmitter can deliver more than 15dBm Tx power at EVM < 5.6% with a 54Mbps OFDM 802.11g signal. The receiver can provide an IQ signal EVM < 9% with a -74.5dBm 54Mbps OFDM 802.11g signal.

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).

MAX2120 DVB-S Half-NIM Tuner Reference Design

This reference design is a commercial Half-NIM DVB-S tuner that uses Maxim's MAX2120 satellite tuner IC. The reference design connects to the motherboard through a 12-pin connector. The downconverted satellite signal from the LNB is supplied to an active, discrete loop-through, which splits the signal into two paths. One signal goes to the MAX2120 and the other provides an additional output from the STB.

WiBro reference design built with the MAX2837

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.
