The AD8340 vector modulator performs arbitrary amplitude and phase modulation of an RF signal. Because the RF signal path is linear, the original modulation is preserved. This part can be used as a general-purpose RF modulator, a variable attenuator/phase shifter, or a remodulator. The amplitude can be controlled from a maximum of ?2 dB to less than ?32 dB, and the phase can be shifted continuously over the entire 360? range. For maximum gain, the AD8340 delivers an OP1dB of 11 dBm, an OIP3 of 24 dBm, and an output noise floor of ?149 dBm/Hz, independent of phase. It operates over a frequency range of 700 MHz to 1.0 GHz.The baseband inputs in Cartesian I and Q format control the amplitude and phase modulation imposed on the RF input signal. Both I and Q inputs are dc-coupled with a ?500 mV differential full-scale range. The maximum modulation band- width is 230 MHz, which can be reduced by adding external capacitors to limit the noise bandwidth on the control lines.Both the RF inputs and outputs can be used differentially or single-ended and must be ac-coupled. The RF input and output impedances are nominally 50 ? over the operating frequency range. The DSOP pin allows the output stage to be disabled quickly to protect subsequent stages from overdrive. The AD8340 operates off supply voltages from 4.75 V to 5.25 V while consuming approximately 130 mA.The AD8340 is fabricated using the Analog Devices, Inc. proprietary, high performance 25 GHz SOI complementary bipolar IC process. It is available in a 24-lead RoHS-compliant LFCSP package and operates over a ?40?C to +85?C temperature range. Evaluation boards are available.APPLICATIONS RF PA linearization/RF predistortion Amplitude and phase modulation Variable attenuators and phase shifters CDMA2000, GSM/EDGE linear power amplifiers Smart antennas

The AD8363 is a true rms responding power detector that can be directly driven with a single-ended 50 ? source. This feature makes the AD8363 frequency versatile by eliminating the need for a balun or any other form of external input tuning for operation up to 6 GHz.?The AD8363 provides an accurate power measurement, independent of waveform, for a variety of high frequency communication and instrumentation systems. Requiring only a single supply of 5 V and a few capacitors, it is easy to use and provides high measurement accuracy. The AD8363 can operate from arbitrarily low frequencies to 6 GHz and can accept inputs that have rms values from less than ?50 dBm to at least 0 dBm, with large crest factors exceeding the requirements for accurate measurement of WiMAX, CDMA, W-CDMA, TD-SCDMA, multicarrier GSM, and LTE signals.The AD8363 can determine the true power of a high frequency signal having a complex low frequency modulation envelope, or it can be used as a simple low frequency rms voltmeter. The high-pass corner generated by its internal offset-nulling loop can be lowered by a capacitor added on the CHPF pin.Used as a power measurement device, VOUT is connected to VSET. The output is then proportional to the logarithm of the rms value of the input. The reading is presented directly in decibels and is conveniently scaled to 52 mV/dB, or approximately 1 V per decade; however, other slopes are easily arranged. In controller mode, the voltage applied to VSET determines the power level required at the input to null the deviation from the setpoint. The output buffer can provide high load currents.The AD8363 has 1.5 mW power consumption when powered down by a logic high applied to the TCM2/PWDN pin. It powers up within about 30 ?s to its nominal operating current of 60 mA at 25?C. The AD8363 is available in a 4 mm ? 4 mm 16-lead LFCSP for operation over the ?40?C to +125?C temperature range.A fully populated RoHS-compliant evaluation board is also available.Applications:Power amplifier linearization/control loopsMulti-Standard, Multi-Carrier Wireless Infrastructure (MCGSM, CDMA,WCDMA, TD-SCDMA, WiMAX, LTE)Transmitter power controls Transmitter signal strength indication (TSSI)RF instrumentation

The LTC3230 is a low noise charge pump DC/DC converter designed to drive 4 Main LEDs and 1 Sub LED, plus two 200mA linear regulators to provide additional system power. The LTC3230 charge pump requires only four small ceramic capacitors and one current set resistor to form a complete LED power supply and current controller.Built-in soft-start circuitry prevents excessive inrush cur- rent during start-up and mode changes. High switching frequency enables the use of small external capacitors. Main and Sub full-scale current settings are programmed by a single external resistor. Charge pump efficiency is optimized based on the voltage across the LED current sources. The part powers up in 1x mode and automatically switches to the next higher mode, 1.5x and subsequently 2x, whenever any LED current source approaches dropout.Two 200mA linear regulators have independent enable and output voltage select pins. Each regulator can be set to one of three pre-selected output voltages with tri-level input pins. The regulators may be enabled independently of the charge pump.The LTC3230 is available in a low profile (0.75mm) 3mm x 3mm 20-lead QFN package.Applications Multi-LED Driver and Dual LDO Supplies for Cell Phone, PDA, Digital Camera and PND Applications?

Demonstration circuit DC1256A is a single-battery standalone battery charger that can support any version ofthe LTC4012 family of parts. The LTC4012 family of charge controller IC’s do not support charge termination for any specific battery chemistry.
