Texas Instruments (TI) has introduced a new ultra-high-speed ADC with what it claims is the industry's widest bandwidth, fastest sampling rate and lowest power consumption. The ADC12DJ5200RF helps engineers achieve high measurement accuracy for 5G testing applications and oscilloscopes and direct X-band sampling for radar applications, says TI. The company is demonstrating the ADC12DJ5200RF in booth #1272 at the International Microwave Symposium (IMS) in Boston this week (June 4-6).
 The ADC12DJ5200RF's 8 GHz bandwidth enables engineers to achieve as much as 20 percent higher analog input bandwidth than competing devices, which gives engineers the ability to directly digitize very high frequencies without the power consumption, cost and size of additional down-conversion. In dual-channel mode, the ADC12DJ5200RF samples at 5.2 GSPS and captures instantaneous bandwidth (IBW) as high as 2.6 GHz at 12-bit resolution. In single-channel mode, the new ultra-high-speed ADC samples at 10.4 GSPS and captures IBW up to 5.2 GHz.

Low-Profile 180 W AC-DC Power Supplies Provide 94% Efficiency
XP Power has launched a new range of 180 W, U-channel AC-DC power supplies that are intended for space-constrained medical (BF), industrial and IT applications. The low-profile devices are just 29.5 mm high and occupy a small 107.6 mm x 62.8 mm footprint, allowing them to be used in high-density designs. The units are suitable for Class I and Class II operation and offer 2 x MOPP (Means of Patient Protection) of isolation while delivering up to 94% efficiency.  The UCP180 series PSUs have an integrated 12 V, 500 mA fan output, eliminating the need for any external driver circuitry. When used in conjunction with a fan delivering 10 CFM airflow, they can deliver 180 W of power to a load---a power density of 14.2 W/in³. They are also suited for use in convection cooled applications where they deliver 120 W (9.4 W/in³). The U-channel construction provides a robust housing, an optional cover is available for applications where the unit may be user-accessible.
