Wideband Pulsed Power Amplifier

RFMD’s new RF3928B is a 65V 380W high power discrete amplifier designed for S-Band pulsed radar, Air Traffic Control and Surveillance, and general purpose broadband amplifier applications. The RF3928B is a matched GaN transistor in a hermetic, flanged ceramic package. This package provides thermal stability through the use of advanced heat sink and power dissipation technologies. Ease of integration is accomplished through the incorporation of simple, optimized matching net-works external to the package that provides wideband gain and power in a single amplifier.

Features of the unit include wideband operation from 2.8GHz to 3.4GHz, advanced GaN HEMT and heat-sink technologies, optimized evaluation board layout for 50Ω operation, integrated matching components for high terminal impedances, and 65V operation typical performance.

Harris XG-25 Portable Radio for First Responders

Harris Corp. has introduced its XG-25™ portable radio for public safety and mission-critical radio users. The XG-25 operates in VHF Project 25 (P25) conventional and analog modes, and in both narrowband and wideband frequencies.

The rugged XG-25 radio provides mission-critical users with improved audio quality, Bluetooth® wireless connectivity, a large, easy-to-read screen and a lightweight design. The XG-25 in the VHF band split (136-174 MHz) will begin shipping in May 2012 with a complete complement of accessories suited to meet a wide variety of mission-critical users’ needs and requirements. It is a P25 Phase 2-ready radio.

The XG-25 radio is capable of operating on the most advanced P25 conventional systems, including voted and linear simulcast systems. The radio also offers a rich P25 conventional feature set, which includes group, individual and emergency call capabilities, packet data, Over-the-Air-Programming (OTAP), status message and GPS. In analog mode, the XG-25 supports traditional signaling protocols such as GE Star© and MDC1200.

Innovation in Electronic Interconnect Systems

Harwin is a manufacturer of standard interconnect components with an enviable reputation for high quality and customer service. Its high reliability Datamate range, a 2mm pitch cable to cable, cable to board and board to board connector family, has been specified for use in harsh operating conditions many times.

Now Harwin has extended Datamate to include miniature, lightweight mixed technology versions. Mix-Tek Datamate range offers a multitude of configurations for signal, power and/or coax, effectively allowing the customer to configure their own Datamate connector, specific to their application, by mixing and matching the required signal, power and/or coax contacts up to a maximum of 50 low frequency contacts or 12 special (coax and power) contacts. Miniature Mix-Tek connectors feature power contacts rated for use at up to 20A – particularly suited to commercial aircraft designs based on an everything always on that necessitate interconnect systems with a high current carrying capability. Datamate’s signal contacts are rated at up to 3A coax contacts are rated at 50ohms.

Embedded Electronics Connector Technology

Onanon, Inc. custom connector plugs integrated into electronic circuits.

Onanon reports the availability of its embedded electronics connector technology to all OEM application markets

Onanon’s unique breadboard automated manufacturing methods have cost effectively produced connectors with low-profile integrated devices in applications as diverse as medical devices and military avionics.

Beginning with terminating resistors, more complex circuits followed. Operational amplifiers were introduced to boost signal strength or to lower impedance to reduce or eliminate EMI and RFI. Low level, high impedance signals distorted by electrical noise can be converted to high level, low impedance signals by placing op-amps on the connector substrate.

Connector embedded op-amps can be used to convert differential signals to single ended signals. The small currents needed to read a thermistor, for example, can then be introduced by the connector’s circuitry.

Low-Cost, High-Performance RF Solution

Agilent Technologies Inc. is offering the latest release of its industry-leading, low-cost, high-performance software for RF and microwave board design, Genesys 2012. The updated software provides enhancements in RF system simulation (including electromagnetic, circuit and statistical simulation), plus features to help designers improve the reliability of their systems.

Genesys 2012 simplifies analysis of RF systems with multi-stage conversions that enable system architects to easily visualize spurious signals across a broad frequency sweep.

Along with its unique root-cause-analysis capabilities, Genesys now gives RF system designers unprecedented power to quickly determine the source and path of spurious frequencies across the entire frequency range of the system. This enables efficient troubleshooting of the system architecture and frequency plan during system design, before hardware implementation. That, in turn, eliminates costly hardware rework during system integration.

Fan-and-Filter Units for EMC Enclosures

A new range from Rittal now offers improved shielding or attenuation of electromagnetic fields and thus higher EMC safety.

The new development, which has the advantages of the TopTherm fan-and-filter unit series, such as high pressure stability and easy mounting, meets the requirements of performance category 2 for screening attenuation according to EN61587-3:2006 in the frequency range of 30 to 1000MHz.

What is new is that the entire fan unit – consisting of housing and filter mat – is designed for optimal EMC protection. Although until now special EMC wire gratings were necessary for shielding, users can do without them with the new units. Rittal achieves improved shielding by means of metallised surfaces, both of the filter housings as well as of the filter mats, with copper-nickel-chrome coatings. The EMC fan-and-filter units have a minimum attenuation of 40dB from 30 to 230MHz and 30dB for the frequency range of 230 to 1000MHz.

Low Cost VCO for Satellite Communication Systems

Z-Communications, Inc. is offering the SMV5550B-LF, a high performance VCO that generates frequencies between 5000 and 6000MHz, covering the 1000MHz bandwidth within 0 to 10V of control. Even though the device covers a broad spectrum of bandwidth, the SMV5550B-LF comes in a compact package covering an area less than .10in2 while exhibiting remarkably good phase noise performance of -80dBc/Hz, typically, at 10kHz from the carrier.

The SMV5550B-LF delivers 3 ± 3dBm into a 50W load with a nominal 5V supply and drawing typically 24mA. In addition to its low noise performance, this device also exhibits excellent second harmonic suppression of -35dBc, typically, and provides better than 1.1:1 tuning linearity making it the ideal component for satellite communication systems. Load pulling is furthermore minimized to less than 10MHz with a return loss of 20dB in any phase while it pushes less than 20MHz/V with a 5% change in the nominal supply.
