ADL5386:  50 MHz TO 2200 MHz Quadrature Modulator with Integrated Detector and VVA

Product Details

Product Status:Recommended for New Designs

The ADL5386 is a quadrature modulator with unmatched integration levels for low intermediate frequency (IF) and radio frequency (RF) transmitters within broadband wireless access systems, microwave radio links, cable modem termination systems, and cellular infrastructure equipment. The ADL5386 operates over a frequency range of 50 MHz to 2200 MHz. Its excellent phase accuracy and amplitude balance supports high data rate, complex modulation for next-generation communication infrastructure equipment.

In addition, the ADL5386 incorporates a standalone logarithmic power detector, as well as a voltage variable attenuator (VVA). The attenuator has its own separate input and output pins for easy cascading with filters and buffer amplifiers. The wide dynamic range of the power detector and VVA provides flexibility in the choice of the signal monitoring point in the transmitter system.

The wide baseband input bandwidth of 700 MHz allows for either baseband drive or a drive from a complex IF signal. Typical applications are in IF or direct-to-RF radio-link transmitters, cable modem termination systems, broadband wireless access systems, and cellular infrastructure equipment.

The ADL5386 takes signals from two differential baseband inputs and modulates them onto two carriers in quadrature with each other. The two internal carriers are derived from a single-ended, external local oscillator (LO) input signal at twice the frequency as the desired output. The output amplifier is designed to drive a 50 Ω load.

The ADL5386 consists of two die, one fabricated using the Analog Devices, Inc., advanced SiGe bipolar process, and the other using an external GaAs process. The ADL5386 is packaged in a 40-lead, Pb-free LFCSP_VQ with an exposed paddle. Performance is specified over the −40°C to +85°C range. A Pb-free evaluation board is also available.

Recommended PLL's for the ADL5386

  • 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 ADL5386
  • For the full listing of frequency and driving level options, we recommend the ADL5xxx selection table.
Recommended Differential Dual Baseband TxDAC's for the ADL5386
  • 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.
