GENERAL DESCRIPTION

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.
