Using quadrature sampling architecture, Linear Technology has developed a wideband RF-to-digital µModule (micromodule) receiver that is capable of digitizing fifth order intermodulation distortion signals to enable a digital predistortion receiver with very wide bandwidth. The highly-integrated receiver is aimed at wideband, low IF receivers, and wireless base stations implementing power amplifier (PA) linearization with digital predistortion (DPD).

MITEQ's SAFSW Series of K-Band Waveguide Amplifiers offer very low noise figure [1.25 dB @+25° C from 18 to 21 GHz] operation in extreme airborne environments. An integral transmit band filter can also supply 60 dB minimum of rejection at 30 GHz. MITEQ's design can be powered by either +12 to +15 VDC or +5 VDC for minimum power dissipation.

Today's state-of-the-art wireless sensor networks have lower deployment and maintenance costs, last longer, and are more rugged.

Targeting high data-rate wireless back-haul communication links, Infineon Technologies AG has introduced a new millimeter-wave transceiver family that simplifies system design by replacing more than ten discrete devices. Fabricated using silicon germanium (SiGe) technology, the new devices provide a complete RF front-end for wireless communication in the V- and E-band millimeter-wave frequencies.

WorkHorse® coaxial assemblies are a reliable and cost-effective group of test assemblies. These ruggedized cables were designed for use in high-volume production environments where strenuous flexing and numerous mating cycles quickly destroy typical connectors and attachment methods. WorkHorse assemblies are ideal replacements for OEM test port cables due to their long life and repeatable performance.

Tech-Etch offers one and two-piece board level shielding with shield heights as low as .060 in. that incur no tooling charges. The photoetching process provides complete design freedom and fast delivery. Prototypes in as few as five days. Download Board Level Shielding Configurable PDF Sales Drawings.

Anatech Electronics' multiband multiplexers combine transmit and receive paths into a single antenna or split signals from a single antenna into multiple base stations.

They can combine or split two ways (duplexer) or three ways (triplexer) with up to six wireless bands in any combination, regardless of the wireless standard.

Peregrine Semiconductor Corp. has launched an AEC-Q100 Grade 2 certified single-pole, double-throw (SPDT) RF switch for designs that have to operate in harsh automotive environments. The UltraCMOS-based switch is qualified for operation across the extended automotive temperature range with the ability to withstand stress tests for an extended period of time. Plus, it offers low insertion loss and high isolation.

In partnership with Mini-Circuits, Modelithics is developing high-accuracy EDA simulation models of Mini-Circuits' surface-mount microwave precision fixed attenuators, the YAT and RCAT Series. The high-frequency substrate-scalable models are currently in development and are expected to be available later in the second quarter. They can be downloaded free-of-charge from the Modelithics' Web site. In addition, the models will also be included in Modelithics' complimentary SELECT PLUS version of its library of advanced RF and microwave simulation models.

Pasternack Enterprises' new RF cable assemblies are hand-formable semi-rigid replacements that are an ideal alternative to costly preformed coaxial assemblies. These formable cables are dimensionally and electrically similar to their semi-rigid counterpart and have a tinned-copper-braid outer shield that provides excellent RF shielding. In addition, the new cables do not require special tooling to shape or reshape assemblies.

Maxim Integrated Products has released a new RF-to-Bits tuner for digital audio broadcast (DAB) applications in automobiles and other mobile products. The tuner integrates a radio tuner, analog-to-digital converter, and digital filtering, and uses a digital I²S output to interface directly to DSPs. This architectural partition facilitates faster development times and seamless software-based upgrades.

Fabless semiconductor company BeSpoon and French R&D organization CEA-Leti have jointly developed an impulse radio ultra-wideband (IR-UWB) transceiver IC capable of measuring distances within a few centimeters' accuracy. It combines RF front-end and digital base band on-chip to overcome the limited operating range of the CMOS transceiver. Also, the chip is designed for integration within smartphones or set-top boxes.
