Analog Devices Inc.The LT3027 is a dual, micropower, low noise, low dropout regulator with independent inputs. With an external 0.01?F bypass capacitor, output noise is a low 20?VRMS over a 10Hz to 100kHz bandwidth.

Shutdown control is independent for each channel, allowing for flexibility in power management. The device is capable of operating over an input voltage from 1.8V to 20V, and can supply 100mA of output current from each channel with a dropout voltage of 300mV. Quiescent current is well controlled in dropout.The LT3027 regulator is stable with output capacitors as low as 1?F. Small ceramic capacitors can be used without the series resistance required by other regulators.Internal protection circuitry includes reverse battery protection, current limiting and thermal limiting protection. The device is available as an adjustable device with a 1.22V reference voltage. The LT3027 regulator is available in the thermally enhanced 10-lead MSOP and low profile (0.75mm) 3mm ? 3mm DFN packages.Applications Cellular Phones Pagers Battery-Powered Systems Frequency Synthesizers Wireless Modems Tracking/Sequencing Power Supplies

The delay between regulated output level and flag indication is programmable with a single capacitor. The LT3013 also has the ability to operate with very small output capacitors. The regulator is stable with only 3.3?F on the output while most older devices require between 10?F and 100?F for stability. Small ceramic capacitors can be used without any need for series resistance (ESR) as is common with other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting and reverse current protection.The device is available with an adjustable output with a 1.24V reference voltage.

Analog Devices Inc.The LT5518 is a direct I/Q modulator designed for high performance wireless applications, including wireless infrastructure. It allows direct modulation of an RF signal using differential baseband I and Q signals. It supports PHS, GSM, EDGE, TD-SCDMA, CDMA, CDMA2000, W-CDMA and other systems. It may also be configured as an image reject up-converting mixer, by applying 90? phase-shifted signals to the I and Q inputs. The high impedance I/Q baseband inputs consist of voltage-to-current converters that in turn drive double-balanced mixers. The outputs of these mixers are summed and applied to an on-chip RF transformer, which converts the differential mixer signals to a 50? single-ended output. The balanced I and Q baseband input ports are intended for DC coupling from a source with a common mode voltage level of about 2.1V. The LO path consists of an LO buffer with single-ended input, and precision quadrature generators that produce the LO drive for the mixers. The supply voltage range is 4.5V to 5.25V.Applications Infrastructure Tx for DCS, PCS and UMTS Bands Image Reject Up-Converters for DCS, PCS and UMTS Bands Low Noise Variable Phase-Shifter for 1.5GHz to 2.4GHz Local Oscillator Signals
