devices from Analog Devices are a paired highly integrated microwave upconverter and
downconverter, respectively. These ICs operate over a very wide frequency range with 50 Ω-match from 24 GHz up
to 44 GHz, facilitating ease of design and reducing the costs of building a single platform that can cover all
5G mm Wave frequency bands including 28 GHz and 39 GHz. Additionally, the chipset is capable of flat 1 GHz RF
instantaneous bandwidth supporting all broadband services as well as other ultra-wide bandwidth transceiver
is highly integrated, comprising I (in-phase) and Q
(quadrature-phase) mixers with on-chip programmable quadrature phase-shifter configurable for direct conversion
to/from baseband (operable from DC to 6 GHz) or to an IF (operable from 800 MHz to 6 GHz). Also included on-chip
are voltage variable attenuators, transmit PA driver (in the upconverter) and a receive LNA (in the downconverter),
LO buffers with x4 frequency multiplier and programmable tracking filters.
Most programmability functions of the
devices are controlled via an SPI serial interface.
Through this port, these chips also provide a unique capability for each upconverter and downconverter to correct
its respective quadrature phase imbalance, hence the usually difficult to suppress sideband emission can be improved
from a typical value of 32 dBc, by 10 dB or more. This results in an unmatched level of microwave radio performance.
The combination of features provides unprecedented flexibility and ease of use while minimizing external components,
enabling implementation of small form factor systems such as small cells.
The highly integrated
microwave upconverter and the
microwave downconverter are ideally suited for
the microwave radio platforms that operate in the emerging 28 GHz and 39 GHz 5G wireless infrastructure bands. The
converters’ 1GHz bandwidth capability, along with the upconverter’s OIP3 of more than 20 dBm that supports stringent
modulation schemes such as 1024QAM, are necessary to enable multi-Gigabit wireless data. Moreover, the chipset
benefits other applications such as satellite and earth station broadband communication links, aircraft radios, RF
test equipment and radar systems. Their superb linearity and image rejection performance are particularly compelling
for improved range of microwave transceivers.
is offered in a 40-pin, 6mm x 6mm LGA, and the
is in a 32-pin, 5mm x 5mm LGA package, both devices have an operating temperature range of −40°C to +85°C.
Typical applications include Point to point microwave radios, Radar, Electronic warfare systems, Instrumentation and
Automatic test equipment (ATE).
Analog Devices also have evaluation boards available for the
up & downconverters to help designers
quickly evaluate the performance of the devices. The
evaluation boards incorporate the
devices respectively along with a microcontroller, low dropout (LDO) regulators, and nanoDAC® to
allow the quick and easy evaluation of the devices. The on-board microcontroller allows the user to configure the register
map of the devices through the Analysis, Control, Evaluation (ACE) software. The LDO regulators allow the
to be powered on by a single supply, and offer power supply ripple rejection. The nanoDAC allows the user to
attenuate the radio frequency (RF) power from the mixer of the
without using an external power supply.
