ADL5375:  400 MHz TO 6 GHz Broadband Quadrature Modulator

Product Details


The ADL5375 is a broadband quadrature modulator designed for operation from 400 MHz to 6 GHz. Its excellent phase accuracy and amplitude balance enable high performance intermediate frequency or direct radio frequency modulation for communication systems.

The ADL5375 features a broad baseband bandwidth, along with an output gain flatness that varies no more than 1 dB from 450 MHz to 3.8 GHz. These features, coupled with a broadband output return loss of <−14 dB, make the ADL5375 ideally suited for broadband zero IF or low IF-to-RF applications, broadband digital predistortion transmitters, and multiband radio designs.

The ADL5375 accepts two differential baseband inputs and a single-ended LO. It generates a single-ended 50 Ω output. The two versions offer input baseband bias levels of 500 mV (ADL5375-05) and 1500 mV (ADL5375-15).

The ADL5375 is fabricated using an advanced silicon-germanium bipolar process. It is available in a 24-lead, exposed paddle, Pb-free, LFCSP_VQ package. Performance is specified over a −40°C to +85°C temperature range. A Pb-free evaluation board is also available.

Recommended PLL's for the ADL5375

  • 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 ADL5375 Recommended Differential Dual Baseband TxDAC's for the ADL5375
  • 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 Low-Noise Voltage Regulators for the ADL5375
  • For a fixed 5V, 500mA low dropout regulator with reverse current protection, we recommend the ADP7104.
Recommended Power Solutions
  • For selecting voltage regulator products, use ADIsimPower.
