Cost effective due its silicon-germanium (SiGe) construction, the 60 GHz development system and transceiver modules from Pasternack enable experimentation and development in the globally-unlicensed 60 GHz ISM frequency band.
Pickering Interfaces is expanding its range of PCI and PXI Programmable Resistors. The existing PCI High-Density Precision Resistor Card (model 50-297) and PXI High-Density Precision Resistor Module (model 40-297) have been expanded to increase the versions offered from 6 to 42; each version offers users the choice of the number of resistor channels, resistance range and the resistance setting resolution.
Richardson RFPD Inc. announces immediate availability and full design support capabilities for a new RF Agile Transceiver™ from Analog Devices, Inc. (ADI). The AD9364 is a high-performance, highly-integrated radio frequency (RF) agile transceiver designed for use in 3G and 4G base station applications. The device combines an RF front-end with a flexible mixed-signal baseband section and integrated frequency synthesizers.
Pickering Interfaces, a leading provider of modular signal switching and instrumentation for use in electronic test and simulation, is improving and expanding its range PXI Microwave Switching Modules. All of these new and improved microwave switch modules will include visual indicators of the relay setting thru the use of blue LEDs that indicate when a normally open path has been closed.
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.
