ADL5385ACPZ-WP: 50 MHz to 2200 MHz Quadrature Modulator
The ADL5385 is a silicon, monolithic, quadrature modulator that is designed for use from 50 MHz to 2200 MHz. Its excellent phase accuracy and amplitude balance enable high-performance IF or direct RF modulation for communication systems.
The AD5385 takes the signals from two differential baseband inputs and modulates them onto two carriers in quadrature with each other. The two internal carriers are derived from a single-ended, external local oscillator input signal at twice the frequency as the desired carrier output. The two modulated signals are summed together in a differential-to-single-ended amplifier designed to drive 50 Ω loads.
The ADL5385 can be used as either an IF or a direct-to-RF modulator in digital communication systems. The wide baseband input bandwidth allows for either baseband drive or drive from a complex IF. Typical applications are in radio-link transmitters, cable modem termination systems, and broadband wireless access systems. The ADL5385 is fabricated using the Analog Devices, Inc., advanced silicon germanium bipolar process and is packaged in a 24-lead, Pb-free LFCSP_VQ with exposed paddle. Performance is specified over –40°C to +85°C. A Pb-free evaluation board is also available.
