The ADL5324 incorporates a dynamically adjustable biasing circuit that allows for the customization of OIP3 and P1dB performance from 3.3 V to 5 V, without the need for an external bias resistor. This feature gives the designer the ability to tailor driver amplifier performance to the specific needs of the design. This feature also creates the opportunity for dynamic biasing of the driver amplifier where a variable supply is used to allow for full 5 V biasing under large signal conditions, and then reduced supply voltage when signal levels are smaller and lower power consumption is desirable. This scalability reduces the need to evaluate and inventory multiple driver amplifiers for different output power requirements, from 25 dBm to 29 dBm output power levels.The ADL5324 is also rated to operate across the wide temperature range of ?40?C to +105?C for reliable performance in designs that experience higher temperatures, such as power amplifiers. The ? W driver amplifier also covers the wide frequency range of 400 MHz to 4000 MHz, and only requiresa few external components to be tuned to a specific band within that wide range. This high performance broadband RF driver amplifier is well suited for a variety of wired and wireless applications, including cellular infrastructure, ISM band power amplifiers, defense equipment, and instrumentation equipment. A fully populated evaluation board is available.The ADL5324 also delivers excellent ACPR vs. output power and bias voltage. The driver can deliver greater than 17 dBm of output power at 2140 MHz, while achieving an ACPR of ?55 dBc at 5 V. If the bias is reduced to 3.3 V, the ?55 dBc ACPR output power only minimally reduces to 15 dBm.Applications Wireless infrastructure Automated test equipment ISM/AMR applications

The ADL5331 is a high performance, voltage-controlledvariable gain amplifier/attenuator for use in applications with frequencies up to 1.2 GHz. The balanced structure of the signal path maximizes signal swing, eliminates common-mode noiseand minimizes distortion while it also reduces the risk of spurious feed-forward at low gains and high frequencies caused by parasitic coupling. The 50 ? differential input system converts the applieddifferential voltage at INHI and INLO to a pair of differentialcurrents with high linearity and good common-mode rejection. The signal currents are then applied to a proprietary voltage-controlled attenuator providing precise definition of the overall gain under the control of the linear-in-dB interface. The GAIN pin accepts a voltage from 0 V at a minimum gain to 1.4 V at afull gain with a 40 mV/dB scaling factor over most of the range.The output of the high accuracy wideband attenuator is appliedto a differential transimpedance output stage. The output stageprovides a differential output at OPHI and OPLO, which must be pulled up to the supply with RF chokes or a center-tapped balun.The ADL5331 consumes 240 mA of current including the output pins and operates off a single supply ranging from 4.75 V to 5.25 V. A power-down function is provided by applying alogic low input on the ENBL pin. The current consumption inpower-down mode is 250 ?A.The ADL5331 is fabricated on an Analog Devices, Inc., proprietary high performance, complementary bipolar IC process.The ADL5331 is available in a 24-lead (4 mm ? 4 mm), Pb-freeLFCSP package and is specified for operation from ambient temperatures of ?40?C to +85?C. An evaluation board is also available.Applications Transmit and receive power control at RF and IF CATV distribution

The ADL5382 is a broadband quadrature I-Q demodulator that covers an RF input frequency range from 700 MHz to 2.7 GHz. With a NF = 14 dB, IP1dB = 14.7 dBm, and IIP3 = 33.5 dBm at 900 MHz, the ADL5382demodulator offers outstanding dynamic range suitable for the demanding infrastructure direct-conversion requirements. The differential RF inputs provide a well-behaved broadband input impedance of 50 ? and are best driven from a 1:1 balun for optimum performance.Excellent demodulation accuracy is achieved with amplitude and phase balances ~0.05 dB and ~0.2?, respectively. The demodulated in-phase (I) and quadrature (Q) differential outputs are fully buffered and provide a voltage conversion gain of ~4 dB. The buffered baseband outputs are capable of driving a 2 Vp-p differential signal into 200 ?.The fully balanced design minimizes effects from second-order distortion. The leakage from the LO port to the RF port is 60 dBm.The ADL5382 operates off a single 4.75 V to 5.25 V supply. The supply current is adjustable with an external resistor from the BIAS pin to ground.The ADL5382 is fabricated using the Analog Devices, Inc., advanced Silicon-Germanium bipolar process and is available in a 24-lead exposed paddle LFCSP. Performance is specified over a -40?C to +85?C temperature range.APPLICATIONS QAM/QPSK demodulator W-CDMA/CDMA/CDMA2000/GSM Point-to-(Multi)Point Radio WiMax

The ADL5390 vector multiplier consists of a matched pair of broadband variable gain amplifiers whose outputs are summed. The separate gain controls for each amplifier are linear-in-magnitude. If the two input RF signals are in quadrature, the vector multiplier can be configured as a vector modulator or as a variable attenuator/phase shifter by using the gain control pins as Cartesian variables. In this case, the output amplitude can be controlled from a maximum of +5 dB to less than -30 dB, and the phase can be shifted continuously over the entire 360? range. Since the signal paths are linear, the original modulation on the inputs is preserved. If the two signals are independent, then the vector multiplier can function as a 2:1 multiplexer or can provide fading from one channel to another.The ADL5390 operates over a wide frequency range of 20 MHz to 2400 MHz. For a maximum gain setting on one channel at 380 MHz, the ADL5390 delivers an OP1dB of 11 dBm, an OIP3 of 24 dBm, and an output noise floor of -148 dBm/Hz. The gain and phase matching between the two VGAs is better than 0.5 dB and 1?, respectively, over most of the operating range.The ADL5390 is fabricated on Analog Devices' proprietary, high performance 25 GHz SOI complementary bipolar IC process. It is available in a 24-lead, Pb-free CSP package and operates over a -40?C to +85?C temperature range.

The LTC3626 is a high efficiency, monolithic synchronous buck regulator using a phase-lockable controlled on-time, current mode architecture capable of supplying up to 2.5A of output current. The operating supply voltage range is 3.6V to 20V, making it suitable for a wide range of power supply applications.The operating frequency is programmable from 500kHz to 3MHz with an external resistor allowing the use of small surface mount inductors. For applications sensitive to switching noise, the LTC3626 can be externally synchronized over the same frequency range. An internal phase-locked loop aligns the on-time of the top power MOSFET to the internal or external clock. This unique controlled on-time architecture is ideal for high step-down ratio applications that demand high switching frequencies and fast transient response. An internal phase lock loop servos the on-time of the internal one-shot timer to match the frequency of the internal clock or an applied external clock.The LTC3626 offers two operational modes: Burst Mode and forced continuous mode to allow the user to optimize output voltage ripple, noise and light load efficiency for a given application.Applications Distributed Power Systems Battery-Powered Instruments Point-of-Load Power Supply
