Cellular module targets CDMA450 networks
Designed specifically for applications in areas where CDMA450 coverage exists as a commercial mobile network operation or where it can be licensed to be developed as a private network, the CE910-SL cellular module has been introduced by Telit Wireless Solutions.
Dual band wireless outperforms fibre-optics
Dual band wireless technology outperforms fibre-optic communication links with single-antenna capability for reduced footprint and greater security. By David Rizzo, Renaissance Electronics.
Crystals enable ECUs to operate at higher frequencies
Suitable for next-gen automotive LANs, such as Ethernet or image processing ECUs, ADAS ECUs and gateway ECUs, the XRCGB-F-A series crystal units have been announced by Murata. The crystals are compact, 2016-size (2.0x1.6mm), and highly precise while supporting high frequencies from 24 to 48MHz.
LNA & PA driver enable 802.11ac applications
Designed for WLAN access points, the GRF2505 LNA and the GRF2541 PA driver have been released by Guerrilla RF. Providing ultra-low noise and high linearity across a 5-6GHz bandwidth, the GRF2505 can be used as either an LNA or as a PA driver for 802.11ac applications. The device’s high IP3 and compression point make it suitable for use as a PA driver, while its low NF of 0.8dB make it suitable as an LNA.
77GHz radar sensor targets harsh environments
A 77GHz radar sensor, designed for use in harsh environments, has been released by Sivers IMA. Suitable for conditions such as fog, smoke or gas, the RS3400W04-A offers an alternative solution to lasers, ultrasound or video-based devices. The sensor features small antennas, making it suitable for applications with a limited space.
Connector offers high pin count in a 2.0mm pitch
Designed to handle demanding automotive conditions, the GT8E series internal wire-to-board or wire-to-wire interface connector has been released by Hirose. Featuring a 2.0mm pitch, the connector provides a high pin count in a small footprint.
LNA operates across a 700-2700MHz bandwidth
Designed for small cells, macro base stations, DAS and other wireless devices in the 700-2700MHz band, the GRF2104 LNA has been released by Guerrilla RF. With a flat gain of 20dB, the device offers outstanding NF and linearity across the 700-2700MHz bandwidth. Internal pre-matching to 50Ω provides users with a compact, low-cost solution, while flexible biasing enables high levels of reuse within a design and across platforms.
In the driving seat
The use of MCUs in automotive applications is growing, but Steve Rogerson found there were differences in how the chip makers see the market evolving.
Bias-Ts can handle multiple 20kA (8/20μs) lighting strikes
Designed for installation close to base receiving stations or near to the antenna, the 3410.41.0038 and 3410.41.0039 Bias-Ts have been introduced by HUBER+SUHNER. The devices, which cover the full 690 to 2700MHz LTE bandwidth, inject or extract DC power into or out of a coaxial cable with the appropriate DC voltage and current. As well as LTE installations, the Bias-Ts support GSM and UMTS cellular installations.
Varistors combine circuit protection & EMI/RFI attenuation
Combining circuit protection and EMI/RFI attenuation functions in a single device, the VR20 varistors have been released by AVX. The TransGuard automotive devices are based on the company’s patented multilayer varistor technology, which provides bi-directional transient voltage protection in the on-state and EMI/RFI attenuation in the off-state.
