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.

Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
ADL5386-EVALZ is 4-layer, FR4-based evaluation board. For normal operation, it requires a 5 V/300 mA power supply and the 5 V power supply should be connected to the clip leads labeled VPOS and GND. The LO and baseband inputs (which should be biased at 0.5 V) are applied to edge-mounted SMA-type RF connectors (labeled LO, IP, IN, QP, and QN). The IQ modulator output can be configured to drive the ADL5386's VVA block. Alternatively, the IQ modulator's output can be accessed directly at the SMA connector labeled VMOD. An AGC mode can be implemented using the on-board log detector/controller. DC voltage proportional to die temperature is available at the clip leads labeled TEMP.
Tools & Simulations
ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
