The AD8341 vector modulator performs arbitrary amplitudeand phase modulation of an RF signal. Because the RF signalpath is linear, the original modulation is preserved. This part canbe used as a general-purpose RF modulator, a variable attenuator/phase shifter, or a remodulator. The amplitude can be controlledfrom a maximum of −4.5 dB to less than −34.5 dB, and the phasecan be shifted continuously over the entire 360° range. For maximumgain, the AD8341 delivers an OP1dB of 8.5 dBm, an OIP3of 17.5 dBm, and an output noise floor of −150.5 dBm/Hz,independent of phase. It operates over a frequency range of1.5 GHz to 2.4 GHz.
The baseband inputs in Cartesian I and Q format control theamplitude and phase modulation imposed on the RF inputsignal. Both I and Q inputs are dc-coupled with a ±500 mVdifferential full-scale range. The maximum modulationbandwidth is 230 MHz, which can be reduced by adding externalcapacitors to limit the noise bandwidth on the control lines.
Both the RF inputs and outputs can be used differentially orsingle-ended and must be ac-coupled. The RF input and outputimpedances are nominally 50 Ω over the operating frequencyrange. The DSOP pin allows the output stage to be disabledquickly in order to protect subsequent stages from overdrive.The AD8341 operates off supply voltages from 4.75 V to 5.25 Vwhile consuming approximately 125 mA.
The AD8341 is fabricated on Analog Devices’ proprietary, highperformance 25 GHz SOI complementary bipolar IC process. Itis available in a 24-lead, lead-free LFCSP package and operatesover a −40°C to +85°C temperature range. Evaluation boardsare available.
