The ADL5385ACPZ-R7 is a silicon, monolithic, quadrature modulatordesigned for use from 30 MHz to 2200 MHz. Its excellent phaseaccuracy and amplitude balance enable both high performanceintermediate frequency (IF) and direct radio frequency (RF)modulation for communication systems.
The ADL5385ACPZ-R7 takes the signals from two differential basebandinputs and modulates them onto two carriers in quadraturewith each other. The two internal carriers are derived from asingle-ended, external local oscillator input signal at twice thefrequency as the desired carrier output. The two modulatedsignals are summed together in a differential-to-single-endedamplifier designed to drive 50 Ω loads.
The ADL5385ACPZ-R7 can be used as either an IF or a direct-to-RFmodulator in digital communication systems. The widebaseband input bandwidth allows for either baseband drive ordrive from a complex IF. Typical applications are in radio-linktransmitters, cable modem termination systems, and broadbandwireless access systems.
The ADL5385ACPZ-R7 is fabricated using the Analog Devices, Inc.,advanced silicon germanium bipolar process and is packaged ina 24-lead, RoHS-compliant LFCSP with exposed pad. Performanceis specified over –40°C to +85°C. A RoHS-compliant evaluationboard is also available.
