Analog Devices’ Broadband
Quadrature Modulator is Industry’s
First to Integrate Automatic Gain
Control
- ADI’s ADL5386 provides a complete solution for cable and wireless
infrastructure applications.
NORWOOD, Mass.--(BUSINESS
WIRE)-- Analog Devices, Inc. (ADI), a world leader in semiconductors
for signal processing applications, today introduced the industry’s
first high-performance broadband
I/Q quadrature modulator to integrate automatic gain control (AGC)
circuitry within a compact 6-mm × 6-mm LFCSP (lead-frame chip-scale
package). ADI’s
ADL5386 provides a unique combination of performance and unmatched
integration levels for low IF (intermediate frequency) and RF (radio
frequency) transmitters within broadband wireless access systems, microwave
radio links, cable modem termination systems and cellular infrastructure
equipment.
Operating over a 50-MHz to 2200-MHz frequency range,
the ADL5386 supports high-data-rate complex modulation for next-generation
communication infrastructure equipment. Functionally complete, the ADL5386
integrates a 25-dB dynamic range output power detector and a VVA (voltage
variable attenuator). Together, they form a closed-loop automatic level
control (ALC) or AGC, enabling the ADL5386 to accurately set the output
power to a user determined level. The ADL5386 provides a complete subsystem
within a small footprint, saving considerable board space, component
cost, and circuit complexity over discrete implementations.
ADL5386 Eases Broadband High-Data-Rate Next-Generation Radio Applications
The ADL5386 provides exceptional output dynamic range due to
its high output power capability (+10 dBm P1dB), high single-ended output
linearity (+24 dBm IP3), and low noise floor (–160 dBm/Hz). The –38
dBm carrier feedthrough and –46 dBc sideband suppression at 350 MHz
minimizes the need for calibration and nulling in complex high-order
modulation applications such as 64 QAM (quadrature amplitude modulation)
and greater.
The ADL5386 wideband inputs (dc to 700 MHz) are
compatible with the output levels of ADI’s
AD977x family of TxDAC+® (transmit digital-to-analog converter)
devices. The –7 dBm local oscillator (LO) drive requirement is compatible
with ADI’s
ADF4360 series of integrated PLL (phase locked loop) synthesizers.
The 2 × LO input frequency of the ADL5386 helps to minimize LO pulling
in applications where LO isolation and board density are critical.
Availability and Pricing
The ADL5386
is in full-production and is available in a 40-pin LFCSP. The ADL5386
is priced at $5.29 per unit in 1,000-unit quantities. For more information,
