Description
AI
The ADL5370 is the first in the fixed-gain quadrature modulator (F-MOD) family designed for use from 300 MHz to 1000 MHz. Its excellent phase accuracy and amplitude balance enable high performance intermediate frequency or direct radio frequency modulation for communication systems.The ADL5370 provides a greater than 500 MHz, 3 dB baseband bandwidth, making it ideally suited for use in broadband zero IF or low IF-to-RF applications and in broadband digital predistortion transmitters.The ADL5370 accepts two differential baseband inputs and a single-ended LO and generates a single-ended 50 Ω output.The ADL5370 is fabricated using the Analog Devices, Inc. advanced silicon-germanium bipolar process. It is available in a 24-lead, exposed-paddle, Pb-free, LFCSP package. Performance is specified over a −40°C to +85°C temperature range. A Pb-free evaluation board is available.ApplicationsCellular communication systems at 450 MHz CDMA2000/GSMWiMAX/broadband wireless access systemsCable communication equipmentSatellite modems
