detector has been introduced by Linear Technology Corporation. It provides accurate, true power measurement of RF and microwave signals independent of modulation and waveforms. The LTC5596 responds in log-linear 29mV/dB scale to signal levels from –37dBm to –2dBm, at
used, from 100MHz to 40GHz, however with slightly reduced accuracy at the frequency extremes. Its RF input is internally 50Ω matched from 100MHz to 40GHz, making the device very easy to use at any band within its frequency range. This devices particularly wide
bandwidth allows the detector to work seamlessly across multiple frequency bands using a common design with minimum calibration. For example, the LTC5596 works equally
well in a sub-10GHz backhaul microwave link as with a 28GHz version. A single design with no recalibration has the potential to provide significant cost savings to equipment manufacturers. Moreover, the wide frequency range and improved sensitivity enables use in a wide variety of applications such as radar systems, avionics, wireless infrastructure base stations, satellite communications and test instruments. This device operates from a single
3.3V supply, drawing a nominal supply current of 30mA. The detector has built-in improved ESD protection. All pins are capable of withstanding up to 3,500V discharge, human body model.

CONTACTLESS WIRELESS CHARGING SOLUTION
A contactless wireless charging solution has been released by Renesas Electronics, for low-power applications, such as hearing aids and other wearable devices that require resistance to water and dust. The new solution consists of a power
BLUETOOTH LOW ENERGY MODULES FEATURE ASCII-STYLE COMMAND INTERFACE
Next-generation Bluetooth low energy (BLE) solutions from Microchip Technology are now available from Mouser Electronics, Inc.. The RN4870 and RN4871 modules feature an ASCII-style command interface that makes them easy to configure and eliminates any complicated code compiling. The modules support the latest Bluetooth 4.2 specification and have a Bluetooth stack on board with a scripting engine to enable standalone operation and eliminate microcontroller use for simple applications. These modules deliver up to 2.5 times the data throughput improvement
over previous-generation products based on the Bluetooth 4.0 standard. In addition, they offer Federal Information Processing Standards (FIPS)-based
connection security coupled with advanced features. The modules can seamlessly transfer serial data over BLE devices and can support different beacon formats like iBeacon or Eddystone via a single command. Both modules are available in a variety of packages, including compact options as small as 6×8mm and in shielded or unshielded options, with shielded version fully certified to meet worldwide regulatory standards. This, combined with Microchip’s user-friendly interface, helps speed time to market. Mouser also offers the RN-4870-SNSR development board, which includes an onboard RN4870 module and
antenna with 2dBm output power, sensor board to demonstrate digital and analogue input/output (IO) capabilities, and a mini-USB cable. The RN-4870-SNSR board features Microchip’s PICtail interface for connection to the company’s microcontroller development platforms, such as Explorer 16. Additionally, it is possible to use smartphone apps, such as SmartDiscover, to demonstrate Bluetooth data connections to the module.
