Analog Devices Inc. has announced the ADMV1013 and ADMV1014, a paired highly integrated microwave upconverter and downconverter, respectively.

The ADMV1013 is offered in a 40-pin, six millimetre by 6mm LGA, and the ADMV1014, which is made of silicon germanium, is in a 32-pin, 5mm x 5mm Land Grid Array package. They operate over a very wide frequency range with 50 Ω-match from 24 Gigahertz up to 44 GHz. This facilitates an ease of design and reduces the costs of building a single platform that can cover all 5G network millimetre Wave frequency bands including 28 GHz and 39 GHz. Additionally, the chipset is capable of flat 1 GHz radio frequency instantaneous bandwidth which supports all broadband services as well as a range of ultra-wide bandwidth transceiver applications.

“The combination of features provides unprecedented flexibility and ease of use while minimising external components, enabling implementation of small form factor systems such as small cells,” says ADI. Both the ADMV1013 and the ADMV1014 can be used for point to point microwave radios, automatic test equipment and radar, electronic warfare systems.

Each upconverter and downconverter is highly integrated, comprising an in-phase and a quadrature-phase mixer with on-chip programmable quadrature phase-shifter configurable for direct conversion to and from baseband. They are operable from direct conversion to 6 GHz or an intermediate frequency from 800 MHz to 6 GHz. On the chip is also included voltage variable attenuators, a transmit Power Amplifier (PA) driver in the upconverter and a receive Low Noise Amplifier (LNA) in the downconverter, along with Local Oscillator (LO) buffers with times four frequency multiplier and programmable tracking filters.




SPI serial interface

Most of the programmability functions are controlled via a Serial Peripheral Interface serial interface. Through this, the chips can deliver 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 decibels relative to the carrier (dBc), by 10 decibels (dB) or more. This results in an unmatched level of microwave radio performance.

The highly integrated ADMV1013 microwave upconverter and the ADMV1014 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 Output Intercept Point (OIP)3 of more than 20 decibel milliWatts (dBm) that supports stringent modulation schemes such as 1024QAM, are necessary to enable multi-Gigabit wireless data.

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.
