RFMW Ltd. announces design and sales support for Sangshin Elecom’s KSA series of Globalstar patch antennas. The KSA-LCSP1621MS25 is designed specifically for Globalstar (1611.25 to 1618.75 Mhz) applications. This left hand circularly polarized (LHCP) antenna is tuned / tested for operation at 1621 MHz (5 MHz above the GlobalStar band) to accommodate frequency shifts that may occur in a radome.
Agilent Technologies Inc. expanded the world’s most flexible PNA-X family of network analyzers with an 8.5 GHz model that more economically supports lower-frequency devices used in wireless communication applications (e.g., handsets, base stations, WLAN and other mobile communication devices).
Linear Technology Corp. announces the LT3667, a 400 mA, 40 V step-down switching regulator with dual LDO outputs packaged in a 3 mm x 5 mm QFN or MSOP-16E. The LT3667 offers a highly compact, triple output solution for automotive and industrial applications. The LT3667 operates from a VIN range of 4.3 to 40 V with transient protection to 60 V.
Richardson RFPD, Inc. announces immediate availability and full design support capabilities for a new absorptive RF single-pole four-throw (SP4T) switch from Peregrine Semiconductor Corporation (Peregrine). The broadband, highly linear PE42442 operates from 450 MHz to 4 GHz and features 61 dB isolation (at 900 MHz), +58 dBm IIP3, and +34 dBm power handling.
Linear Technology introduces the LT6020, a dual 3V to 30V fast settling operational amplifier, featuring 30µV maximum input offset voltage and 0.5µV/°C max VOS drift. While supply current is only 100µA maximum per amplifier, proprietary slew enhancement circuitry provides fast clean output step response. The LT6020 settles to 0.0015% in less than 15µs regardless of whether the output step is 5V or 25V. Specially designed input circuitry maintains high impedance, minimizing current spikes associated with fast steps for input steps up to 5V.
The AM748B1188 ceramic bandpass filter has a center frequency of 748 MHz, passband of 740 to 756 MHz, ripple of less than 0.7 dB, insertion loss of 2 dB, return loss greater than 14 dB, and rejection of at least 40 dB. It handles 2 W, has an operating temperature range of -20o to +70o C and measures 17 x 13 x 5.5 mm.
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.
