One of the planet’s most challenging applications is operating in a harsh environment like downhole drilling. Precision equipment designed for this type of application must be able to survive extreme pressure, shock and vibration, as well as offer a small form factor and long battery life. However, perhaps the biggest challenge for design engineers is how protect these functions from the impact of extreme temperatures.

Analog Devices has introduced the HMC1127 and HMC1126 MMIC distributed power amplifiers. Covering the frequency range of 2-50GHz, these power amplifier die simplify system design and improve performance by eliminating the need for RF switches between frequency bands. Each amplifier incorporates I/Os that are internally matched to 50Ω, facilitating easy integration into multi-chip modules.

  A quad-channel protector and two multiplexers offering ±55V overvoltage protection for precision converters, amplifiers and other components that operate from a low voltage of 4.5 up to 36V have been released by Analog Devices.

Car manufacturers strive to make future generations of vehicles safer, smarter and more fuel efficient than their predecessors. To accomplish this, electronics systems continue to increase in number and complexity as more ECUs (Electronic Control Units) are deployed in the vehicle – enabling features such as active noise cancellation, internet connectivity and in-car communications.

Analog Devices has introduced an absorptive SPDT switch specified for the 9kHz to 13GHz frequency band, with high isolation of 48dB and low insertion-loss of 0.6dB at 8GHz operation. The HMC1118LP3DE is the first offering within ADI’s RF and microwave control product portfolio to exhibit the inherent advantages of silicon process technology, which offers critical advantages over legacy GaAs RF switches.

Combining low noise performance, high linearity and low power consumption, Analog Devices has introduced a highly integrated, 4-channel, 24GHz receiver down-converter MMIC, the ADF5904. The multichannel device achieves a 10dB noise figure that is 3dB better than competing devices while using 50% less power, according to ADI, and is assembled in a small, cost-effective 5x5mm LFCSP plastic package.

Analog Devices has introduced a 2.6GHz ADC, engineered to address the high-bandwidth and dynamic-range needs of aerospace and defence applications. The 12-bit AD9625BBP-2.6 is optimised 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.

A FET input AFE, introduced by Analog Devices, integrates an ADC driver to interface directly with current mode sensors such as photo diodes and highoutput impedance-voltage sensors. The ADA4350 integrates a FET input amplifier, switching network and ADC driver into a single package, which simplifies design and lowers power and PCB footprint by more than 50%, compared to discrete implementations.
