Product Details

The ADL5385 is a silicon, monolithic, quadrature modulator designed for use from 30 MHz to 2200 MHz. Its excellent phase accuracy and amplitude balance enable both high performance intermediate frequency (IF) and direct radio frequency (RF) modulation for communication systems.

The ADL5385 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, RoHS-compliant LFCSP with exposed pad. Performance is specified over –40°C to +85°C. A RoHS-compliant evaluation board is also available.

Applications

  • Radio-link infrastructure
  • Cable modem termination systems
  • UHF/VHF radio
  • Wireless infrastructure systems
  • Wireless local loop
  • WiMAX/broadband wireless access systems
