869 MHz TO 960 MHz Quadrature Modulator
This family of monolithic RF quadrature modulators is designed for use from 869 MHz to 960 MHz and from 1805 MHz to 1990 MHz. Excellent phase accuracy and amplitude balance enable high performance, direct RF modulation for communications systems.
The ADL5590 and ADL5591 can be used as direct RF modulators in digital communications systems such as those using the Global System for Mobile Communications (GSM) network. In addition, the parts are compatible with enhanced data rates for GSM evolution (EDGE).
This family is fabricated using an advanced silicon-germanium bipolar process from Analog Devices, Inc., and is available in a 36-lead, exposed paddle LFCSP. The devices operate from −40°C to +85°C.
