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 ADL5504 is a TruPwr? mean-responding (true rms) power detector for use in high frequency receiver and transmitter signal chains from 450 MHz to 6000 MHz. Requiring only a single supply between 2.5 V and 3.3 V, the detector draws less than 1.8 mA. The input is internally ac-coupled and has a nominal input impedance of 500 ?. The rms output is a linear-responding dc voltage with a conversion gain of 1.87 V/V rms at 900 MHz.The ADL5504 is a highly accurate, easy to use means of determining the rms of complex waveforms. It can be used for power measurements of both simple and complex waveforms but is particularly useful for measuring high crest factor (high peak-to-rms ratio) signals, such as W-CDMA, CDMA2000, WiMAX, WLAN, and LTE waveforms.The on-chip modulation filter provides adequate averaging for most waveforms. For more complex waveforms, an external capacitor at the FLTR pin can be used for supplementary signal demodulation. An on-chip, 100 ? series resistance at the output, combined with an external shunt capacitor, creates a low-pass filter response that reduces the residual ripple in the dc output voltage.The ADL5504 offers excellent temperature stability across a 30 dB range and near 0 dB measurement error across temperature over the top portion of the dynamic range. In addition to its temperature stability, the ADL5504 offers low process variations that further reduce calibration complexity.The power detector operates from ?40?C to +85?C and is available in a 6-ball, 0.8 mm ? 1.2 mm, wafer level chip scale package. It is fabricated on a high fT silicon BiCMOS process.Applications Power measurement of W-CDMA, CDMA2000, QPSK-/QAM-based OFDM (LTE and WiMAX), and other complex modulation waveforms RF transmitter or receiver power measurement
