The MAX2015 complete multistage logarithmic amplifier is designed to accurately convert radio-frequency (RF) signal power in the 0.1GHz to 3GHz frequency range to an equivalent DC voltage. The outstanding dynamic range and precision over temperature of this log amplifier make it particularly useful for a variety of base station and other wireless applications, including automatic gain control (AGC), transmitter power measurements, and received signal strength indication (RSSI) for terminal devices.The MAX2015 can also be operated in a controller mode where it measures, compares, and controls the output power of a variable-gain amplifier as part of a fully integrated AGC loop.This logarithmic amplifier provides much wider measurement range and superior accuracy compared to controllers based on diode detectors, while achieving excellent temperature stability over the full -40°C to +85°C operating range.ApplicationsAGC Measurement and ControlCellular Base Station, WLAN, Microwave Link, Radar, and other Military ApplicationsRF Transmitter Power MeasurementRSSI Measurements

MAX200-MAX209, MAX211, and MAX213 are a family of RS-232 and V.28 transceivers with integrated charge pump circuitry for single +5V supply operation.The drivers maintain the ±5V EIA/TIA-232E output signal levels at data rates in excess of 120kbps when loaded in accordance with the EIA/TIA-232E specification.The MAX211 and MAX213 are available in a 28-pin, wide small-outline (SO) package and a 28-pin shrink small- outline (SSOP) package, which occupies only 40% of the area of the SO. The MAX207 is available in a 24-pin SO package and a 24-pin SSOP. The MAX203 and MAX205 use no external components and are recommended for applications with limited circuit board space.ApplicationsBattery-Powered EquipmentHandheld EquipmentPortable Diagnostics Equipment

The MAX2021 low-noise, high-linearity, direct upconversion/downconversion quadrature modulator/demodulator is designed for RFID handheld and portal readers, as well as single and multicarrier 650MHz to 1200MHz GSM/EDGE, cdma2000®, WCDMA, and iDEN®base-station applications. Direct conversion architectures are advantageous since they significantly reduce transmitter or receiver cost, part count, and power consumption as compared to traditional IF-based double conversion systems.In addition to offering excellent linearity and noise performance, the MAX2021 also yields a high level of component integration. This device includes two matched passive mixers for modulating or demodulating in-phase and quadrature signals, two LO mixer amplifier drivers, and an LO quadrature splitter. On-chip baluns are also integrated to allow for single-ended RF and LO connections. As an added feature, the baseband inputs have been matched to allow for direct interfacing to the transmit DAC, thereby eliminating the need for costly I/Q buffer amplifiers.The MAX2021 operates from a single +5V supply. It is available in a compact 36-pin TQFN package (6mm x 6mm) with an exposed pad. Electrical performance is guaranteed over the extended -40°C to +85°C temperature range.ApplicationsCable Modem Termination Systems (CMTS)Digital and Spread-Spectrum Communication SystemsFixed Broadband Wireless AccessGSM 850/GSM 900 EDGE Base StationsMicrowave LinksMilitary SystemsPredistortion Transmitters and ReceiversRFID Handheld and Portal ReadersSingle and Multicarrier cdmaOne™ and cdma2000® Base StationsSingle and Multicarrier WCDMA 850 Base StationsVideo-on-Demand (VOD) and DOCSIS® Compliant Edge QAM ModulationWiMAX Transmitters and Receivers
