Products stability requirements are critical, these low loss cables allow for a 75% lower phase shift due to the precise construction of the cables. This cable configuration offers attenuation levels 20 to 35% lower than comparable mil-spec cables. The RF cable assemblies come equipped with a choice of stainless steel TNC, SMA and N-Type connectors and a heavy duty booting to improve strain relief. www.fairviewmicrowave.com RFID chip IC authenticates goods via NFC The EM4237 IC from EM Microelectronic is claimed to be the first high-secure ISO/ IEC15693 compliant device to guarantee anti-counterfeiting and brand protection. The chip provides a universal identity card and an encrypted tamperproof digital certificate to convey the guarantee of good quality anywhere in the world, to be read by any NFC-enabled smartphone. The device’s security measures are based on public stream cipher technology used to safeguard the memory data integrity and to ensure communication confidentiality between the IC and the reader. The 2k-bit of data memory can be protected by setting the appropriate access conditions and access rights. After a successful mutual authentication process, data communication can optionally be encrypted (secure messaging) and the data integrity can optionally be protected by a 4-byte MAC (Message Authentication Code). Each EM4237 device contains a unique 64-bit identifier and an optional 32-byte ECC based digital certificate. A secure application running on an NFCenabled smartphone can read out these two unique and personalized pieces of information, connect to a server through the cloud, manage the collected data and confirm the authenticity of a good. The 32-bytes digital signature is calculated using the device’s unique 64-bit ID number, a public and a secret key. Further, the EM4237 offers a privacy mode. In this particular mode, the IC remains silent to any received commands from the RFID reader or can return a random UID number that will be used during the next transaction. The on-chip resonant capacitor is of 23.5pF, the same value present on other ISO/IEC15693 devices. The EM4237 does not require any update of existing antenna designs. www.emmicroelectronic.com LTE module tester offers 80 MHz bandwith for RF ICs Advantest has expanded its T2000 platform with two test modules for RF ICs as they are commonly used in cellphones and WiFi devices. Both are offering a wide bandwidth of 80 MHz, enabling these modules to test according to 802.11ac and LTE-Advanced mobile communications standards. The modules use vector signal generation (VSG) and vector signal analysis (VSA) software to meet the wide-range modulation challenges presented by today’s most advanced portable electronics. Besides their large modulation bandwidth, the modules offer waveform generator software and modulation analysis software for 802.11ac and LTEAdvanced protocols. The modules differ in that the WLS32-A offers 32 ports while the WLS16-A is equipped with just 16 ports. www.advantest.com Oscilloscope covers 200 MHz to 1 GHz with fast acquisition rates With bandwidths from 200 MHz to 1 GHz, RTE digital oscilloscopes from Rohde & Schwarz feature an acquisition rate of over one million waveforms per second to help users find signal faults quickly. The scope’s highly accurate digital trigger system with virtually no trigger jitter delivers highly precise results. The singlecore A/D converter with more than seven effective bits (ENOB) almost completely eliminates signal distortion. With a sampling rate of 5 Gsample per second and a maximum memory depth of 50 Msample per channel, the RTE can accurately record the long signal sequences required when analyzing the data content of serial protocols such as I2C and CAN. Users performing complex tasks will especially appreciate the high measurement speed of the RTE. Mask tests, for example, quickly return statistically conclusive results. The highly responsive, spectrum-analyzer-like FFT reliably detects even sporadic signals, making the oscilloscope ideal for EMI debugging during product development. Innovative tools help users boost their productivity. The QuickMeas function simultaneously performs several measurements on a signal. Fingertip zoom allows users to simply swipe a signal’s zoom area to quickly view signal details. Tools are selected from a configurable toolbar. Rohde & Schwarz also offers a wide range of dedicated application solutions for the RTE, including trigger and decoder options for serial protocols, a mixed-signal option with 16 additional digital channels and a power analysis option. A broad probe portfolio rounds out the offering. The RTE can be ordered with two or four channels and a bandwidth of 200 MHz, 350 MHz, 500 MHz or 1 GHz. www.scope-of-the-art.com www.rohde-schwarz.com Dual-polar ‘White Space’ UHF sector antenna Cobham Antenna Systems, Microwave Antennas (Cobham has developed a dual-polar UHF sector antenna for use in the ‘White Space’ frequency bands.
