The AB950B603 cavity bandpass filter has a center frequency of 950 MHz, passband of 940 to 960 MHz, insertion loss of 0.7 dB, return loss of 18 dB, and operating temperature range of -40o to +85o C. The filter will withstand shock of 20 G (11 ms) and vibration of 20 G, measures 6.6 x 3.5 x 1.5 in., and uses Type-N female connectors.
The AD830-875D207 cavity duplexer for GSM applications has a Band 1 passband of 825 to 835 MHz and Band 2 passband of 870 to 880 MHz. Insertion loss is less than 1.3 dB, ripple is less than 0.2 dB, isolation is 90 dB, rejection ranges from 25 dB to 90 dB, and return loss is greater than 20 dB.
RFMW Ltd. announces design and sales support fora 9 W GaN HPA from TriQuint. The TGA2595 supports VSAT and SatCom applications from 27.5 to 31 GHz. 24% power added efficiency highlights this multi-stage amplifier which draws 280 mA from a 20 V supply. The TriQuint TGA2595 offers 39.5 dBm mid-band saturated output power with small signal gain of 23 dB.
Computer Simulation Technology (CST) announces the release of the 2014 version of the electromagnetic simulation tool, CST STUDIO SUITE®. The latest edition has been developed to improve the performance of the solvers and increase the capabilities for hybrid simulation without compromising on usability.
RFMW Ltd. announces design and sales support for Skyworks SMV2026 series of hyperabrupt tuning varactor diodes. The SMV2026-079LF is offered in the SC-79 package while a smaller, SOD-882 package if available for space constrained layouts. Low series resistance of 0.5 ohm at 5 V typifies this Skyworks varactor series and enables low phase noise in wideband VCO designs.
eSeries connectors are characterized by their physical appearance and innovative cable-to-connector transition style. Externally, eSeries connectors have an extended ferrule designed to protect a common failure point at the solder-wick line when cables are flexed repeatedly. To solve a common problem of brass coupling nuts "walking off," these connectors also feature a new, failure-proof coupling nut.
Rogers Corp. advanced circuit materials division launched COOLSPAN® Thermally & Electrically Conductive Adhesive (TECA) Film providing reliable high temperature performance. COOLSPAN TECA Film is a thermosetting, epoxy based, silver filled adhesive film used to bond circuit boards to heavy metal backplanes, heat sink coins and RF module housings.
Cernex’s CBF series band pass filter is primarily used for narrow band applications. Pass bands are typically from 1% to 4%. The CBF series band pass filter can be designed from 3 to 170 GHz up to 30% bandwidths in 16 waveguide bands. Insertion losses are typically in the 0.8 dB to 2.0 dB area depending upon rejection levels.
Visual System Simulator™ (VSS) is a complete software suite for today’s complex communication systems that enables engineers to design the right system architecture and formulate suitable specifications for each of the underlying components. VSS is built upon Unified Data Model™ architecture (as is Microwave Office®) and therefore provides for seamless system and circuit level co-simulation.
Anritsu Co. announces it has developed the wireless industry’s first PTCRB-approved protocol test case for IMS Emergency Services. This critical test case is now available on the ME7834L Protocol Conformance Test (PCT) and Carrier Acceptance Test (CAT) system. Anritsu recently became the only supplier of approved test cases for this increasingly relevant technology during the PVG#64 meeting held in Beijing.
