Up and Downconverter Pair Offer
24- to 44-GHz Frequency Range

Analog Devices has announced the ADMV1013 and ADMV1014, a paired highly integrated microwave upconverter and downconverter, respectively. These ICs operate over a very wide frequency range with 50 ohm 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 mmWave 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 applications. Each upconverter and downconverter 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).



960 W DIN Rail Supply Boasts 95% Efficiency

TDK has announced the addition of a 960 W rated model to its DRF series of AC-DC DIN rail mount power supplies. The high 95% efficiency produces less internal waste heat enables electrolytic capacitors to run cooler. That enables a calculated life of in excess of eleven years with a 75% load at 230 VAC input. The unit can supply a peak load of 1440 W (24 V 60 A) for up to 4 seconds to power capacitive and inductive loads. Applications include industrial process control, factory automation, and test and measurement equipment.
The power supply has a 24 V output, adjustable from 24 V to 
28 V, using either the front panel mounted trim potentiometer or an external 5 V to 6 V source. The input range is 180 to 264 VAC, withstanding surges of up to 300 VAC for 5 seconds. The operating ambient temperature is -25°C to +70°C, -40°C cold start, derating linearly above 50°C to 75% load at 70°C. The DRF series warranty is five years.

RF-Sampling Transceivers Embed Four ADCs and Four DACs
    
Texas Instruments (TI) has introduced two new RF-sampling transceivers that integrate four analog-to-digital converters (ADCs) and four digital-to-analog converters (DACs) in a single chip. TI says the device offers the industry's widest frequency range, highest instantaneous bandwidth and 75% smaller design footprint than a discrete solution. The quad-channel AFE7444 (shown) and dual-channel AFE7422 transceivers help engineers more easily achieve multiantenna, direct RF sampling for radar, software defined radio and wireless 5G applications.

Offering the highest IBW among radio frequency (RF)-sampling transceivers according to TI, the AFE7444 and AFE7422 enable engineers to achieve up to 600% more data throughput. While sampling up to 9 Gsamples per second (GSPS) per DAC and up to 
3 GSPS per ADC, the AFE7444 receives and transmits up to 
800 MHz of information from each of the four antennae, and the AFE7422 receives and transmits 1.2 GHz from each of the two antennae. The new RF-sampling wideband transceivers give engineers flexibility to design applications covering any frequency from 10 MHz to 6 GHz.
