DC1746A-B: Demo Board for LTM2881 Complete Isolated RS485/RS422 µModule Transceiver + Power.

Demonstration circuit 1793A is a high voltage inverting charge pump with low noise dual-polarity LDO regulators featuring the LTC3260EMSE. The LTC3260 operates with an input voltage from 4.5V to 32V. The demo board provides selectable LDO± output set magnitudes of 3.3V, 5V, 12V and 24V for each polarity. Additional LDO± set point jumper selections and optional topside ADJ± resistors allow the user to set other desired LDO± output voltages. The demo board also provides the means to select between Burst Mode® operation or constant-frequency mode operation, plus select an operating frequency of 500kHz, 200kHz, and 50kHz.

The LTC5507 is an RF power detector for applications operating from 100kHz to 1000MHz. The input frequency range is determined by an external capacitor. A temperature-compensated Schottky diode peak detector and buffer amplifier are combined in a small 6-pin ThinSOT package.The RF input voltage is peak detected using an on-chip Schottky diode and external capacitor. The detected voltage is buffered and supplied to the VOUT pin. A power saving shutdown mode reduces supply current to less than 2?A.Applications Wireless Transceivers Wireless and Cable Infrastructure RF Power Alarm Envelope Detector

DC570A: Demo Board for the LTC2440 24-Bit High Speed Differential Delta Sigma ADC with Selectable Speed/Resolution.

The LTC3722-1/LTC3722-2 phase-shift PWM controllers provide all of the control and protection functions necessary to implement a high efficiency, zero voltage switched (ZVS), full bridge power converter. Adaptive ZVS circuitry delays the turn-on signals for each MOSFET independent of internal and external component tolerances. Manual delay set mode enables secondary side control operation or direct control of switch turn-on delays. The LTC3722-1/LTC3722-2 feature adjustable synchronous rectifier timing for optimal efficiency. A UVLO program input provides accurate system turn-on and turn-off voltages. The LTC3722-1 features peak current mode control with programmable slope compensation and leading edge blanking, while the LTC3722-2 employs voltage mode control. The LTC3722-1/LTC3722-2 feature extremely low operating and start-up currents. Both devices include a full range of protection features and are available in the 24-pin surface mount GN package.Applications Telecommunications, Infrastructure Power Systems Distributed Power Architectures Server Power Supplies

The LT5528 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 con? gured as an image reject up-converting mixer, by applying 90? phase-shifted signals to the I and Q inputs. The 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 four balanced I and Q baseband input ports are intended for DC coupling from a? source with a common-mode voltage level of about 0.5V. 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 PCS and UMTS Bands Low-Noise Variable Phase-Shifter for 1.5GHz to 2.4GHz Local Oscillator Signals
