ADL5374:  3000 MHz TO 4000 MHz Quadrature Modulator

Product Details

The ADL5374 is a member of the fixed-gain quadrature modulator (F-MOD) family designed for use from 3000 MHz to 4000 MHz. Its excellent phase accuracy and amplitude balance enable high performance intermediate frequency or direct radio frequency modulation for communications systems.

The ADL5374 provides a >500 MHz, 3 dB baseband bandwidth, making it ideally suited for use in broadband zero IF or low IF-to-RF applications and for use in broadband digital predistortion transmitters.

The ADL5374 accepts two differential baseband inputs that are mixed with a local oscillator (LO) to generate a single- ended output.

The ADL5374 is fabricated using the Analog Devices, Inc. advanced silicon-germanium bipolar process. It is available in a 24-lead, exposed-paddle, RoHS compliant LFCSP. Performance is specified over a −40°C to +85°C temperature range. A RoHS compliant evaluation board is also available.

    Recommended PLL's for the ADL5374

    • 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 ADL5374
    • For the full listing of frequency and driving level options, we recommend the ADL5xxx selection table.
    Recommended Differential Dual Baseband TxDAC's for the ADL5374
    • 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.
