Analog Devices, Inc. Introduces 2.6-GHz A/D Converter
May 21 15
Analog Devices, Inc. introduced a 2.6-GHz A/D converter engineered to address the high-bandwidth and dynamic-range needs of aerospace and defense applications. Combining giga-sample-rate speed and 75-dBc spurious-free, dynamic-range (SFDR) performance out to 1.8 GHz Ain, the AD9625BBP-2.6 12-bit A/D converter is fully optimized to match the frequency planning and signal sensitivity requirements of advanced electronic surveillance and counter-measure applications, such as radar systems, secure communications networks and electronic signals monitoring. The new converter is available in a tin-lead (SnPb) package that ensures high-reliability operation by eliminating the performance degradation and added cost associated with alternative packaging materials that are susceptible to tin-whiskering.
Analog Devices, Inc. Introduces Highly Integrated, 4-channel, 24-GHz Receiver Downconverter MMIC
May 21 15
Analog Devices, Inc. introduced a highly integrated, 4-channel, 24-GHz receiver downconverter MMIC with the industry’s best combination of low-noise performance, high linearity and low-power consumption. The ADF5904 integrated, multi-channel receiver downconverter achieves a 10-dB noise figure that is 3 dB better than competing devices, while using 50% less power, and is assembled in a small, cost-effective 5 -- 5 mm LFCSP plastic package. Each of the device’s four on-chip receive channels use a simple, single-ended connection to four individual antennas, which simplifies RF-transmission-line design and PCB layout, and reduces board size. The receiver downconverter then simultaneously handles four receive signals directly to produce a high-quality, high-amplitude baseband signal that easily connects to one of ADI’s four-channel analog-to-digital converters. The ADF5904 also incorporates an integrated temperature sensor that eliminates the need for discrete sensing components that otherwise can require additional time and resources to calibrate during system assembly and test. The ADF5904 is designed for multi-channel receiver, high-frequency applications that use digital beam forming, such as automotive ADAS, microwave radar sensors, and industrial radar systems environments where energy efficiency is becoming a more important system-level design consideration. The ADF5904 24-GHz receiver enables these and other sensor applications by offering best-in-class receive sensitivity while using less overall power than competing RF technologies. ADF5904 Receiver Downconverter Key Features; 4 receive channels, Rx channel gain: 22 dB, Noise figure: 10 dB, P1db: -10 dBm, Power consumption: 0.5mW - all 4 channels powered on, LO input range: -8 dBm to +5 dBm, Rx to IF isolation: 30 dB, RF signal bandwidth: 250 MHz and On-chip temperature sensor with analog output: ±5°.
Analog Devices, Inc. Introduces Absorptive Single-Pole, Double-Throw Switch
May 20 15
Analog Devices, Inc. introduced an absorptive single-pole, double-throw (SPDT) switch specified for the 9-KHz to 13-GHz frequency band, with high isolation of 48 dB and low insertion-loss of 0.6 dB at 8-GHz operation. The HMC1118LP3DE is the first offering within ADI’s new RF and microwave control product portfolio to exhibit the inherent advantages of silicon process technology, which offers critical advantages over legacy GaAs (gallium-arsenide) RF switches. These advantages include a settling time that is one hundred times faster than GaAs, robust ESD (electro-static discharge) protection (2000 V vs. 250 V compared to GaAs), and the ability to extend the switch’s low frequency-end one thousand times lower than GaAs while maintaining high linearity. The HMC1118LP3DE also offers RF power handling of 4 W in through and 0.5 W in hot-switching operating modes. Hot-switching power handling is more than two times better than competitive parts with similar RF bandwidth, which allows engineers to increase allowed RF power in their applications and systems without the risk of damage to the part. The HMC1118LP3DE is optimized for high-isolation and extremely flat transfer characteristics within a wide operating frequency range up to 13 GHz, while maintaining high signal fidelity down to 9 kHz. The combination of features suits the switch for demanding test and measurement, automated test equipment, defense electronics, and wireless communication applications as a lower cost alternative to legacy GaAs switches. Pricing and availability HMC1118LP3DE is $6.18. HMC1118LP3DE SPDT Switch key features: Non-reflective 50-ohm design; Positive control: 0/+3.3 V; Low insertion loss: 0.68 dB at 8 GHz; High isolation: 50 dB at 8 GHz; Low-cut off frequency of 9 KHz; Fast settling time of 7.5 usec for 0.05-dB of final RF output level. High-power handling: 35.5-dBm through path and 27-dBm terminated path and hot-switching case. High linearity: P1dB: +37 dBm typical and IIP3: +61 dBm typical. ESD rating: 2-KV HBM.
Analog Devices, Inc. Introduces ADuM4135 Isolated IGBT Gate Driver
May 20 15
Analog Devices, Inc. introduced the ADuM4135 isolated IGBT gate driver to improve electric motor energy efficiency, reliability and system-control performance in industrial motor control applications. Incorporating ADI’s iCoupler® digital isolator technology, the ADuM4135 ensures safety and reliability through proven galvanic isolation in a single package while delivering the industry’s best combination of CMTI (common-mode transient immunity) at 100 kV/µs and propagation delay of 50 ns (typical). The ADuM4135 allows customers to comply with IE3 and IE4 motor efficiency standards, consistent with the industry trend toward higher frequency switching technologies for both motor control and grid-inverters. Safety features include integrated Miller clamping and desaturation detection. System designers can take advantage of the ADuM4135 gate driver’s low propagation delay and skew to minimize dead time between low-side/high-side switching, minimizing losses and improving overall system performance. The breakthrough CMTI performance and low propagation delay also support new power switch technologies, including SiC and GaN, which utilize higher switching frequencies in systems with increased transients. The ADuM4135 is available in a 16-lead, wide-body SOIC package and provides 8-mm creepage and clearance. ADuM4135 Isolated Gate Driver key features: 4-A peak drive output capability, Output power device resistance < 1ohm, Desaturation protection, Isolated desaturation fault reporting, Soft-shutdown on fault, Miller clamp output with gate sense input, Isolated fault and ready functions and Low propagation delay (50 ns typical)/delay skew (15 ns typical).
