ADL5591:  1805 MHz TO 1990 MHz Quadrature Modulator

Product Details

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.

    Recommended PLL's for the ADL5591

    • For high performance with integrated VCO, we recommend the ADF4350.
    • For lower cost, power and size with integrated VCO, we recommend the ADF4360-X family of fixed frequency PLL's.
    • For higher performance, higher frequency and faster locktimes, we recommend the discrete Integer-N, ADF4106 or the discrete Fractional-N, ADF4156.
    Recommended RF/IF Driver Amplifiers and Gain Blocks for the ADL5591
    • For the full listing of frequency and driving level options, we recommend the ADL5xxx selection table.
    Recommended Differential Dual Baseband TxDAC's for the ADL5591
    • For generating differential I and Q currents up to 125MSPS, we recommend the AD911X pin compatible family of low power, small size, TxDAC's like the AD9117.
    • For even lower power requirements up to 125MSPS, we recommend the pin compatible AD971X family of TxDAC's like the AD9717.
    • For higher bandwidths using data rates up to 250MSPS, with low noise and IMD, we recommend the pin compatible AD974X family of CMOS TxDAC's like the AD9747 or AD9125 if interpolation is required.
    • For direct conversion transmit applications up to 500 MSPS, we suggest the pin compatible AD978X family of LVDS TxDAC's like the AD9783 or AD9122 if interpolation is required.
    Recommended Power Solutions

    • For selecting voltage regulator products, use ADIsimPower.
