SPDT RF Switch Delivers High Linearity, Fast Settling Time for ATE, Transceiver Applications Peregrine Semiconductor Corporation has announced the new PE42552 SPDT 50-Ohm RF Switch, designed for use in Test and Measurement (T&M) applications requiring ultra-linear RF performance and ultra-fast settling time, such as Automated Test Equipment (ATE), RF/ IF transceiver signal switching, filter bank switching and discrete digital step attenuator (DSA) stages. Integrated CMOS control logic, driven by a single-pin, low-voltage CMOS control input, features a novel user-defined logic table. Further, the device includes a logic-select pin which inverts logic polarity for backto-back switching applications, changing the logic definition of the control pin. The PE42552, designed on Peregrine’s HaRP-enhanced UltraCMOS silicon-on-sapphire process technology, maintains excellent broadband RF performance from 9 kHz up to 7.5 GHz without gate lag and phase drift, and ensures fast switch-settling time. This innovative feature of the UltraCMOS process provides best-in-class linearity and superior performance to GaAs with the economy an integration of conventional CMOS. “The PE42552 delivers the industry’s fastest settling time and the highest linearity performance available in a RF broadband solid state switch,” stated Mark Schrepferman, product marketing director for commercial and industrial products. “These attributes make the PE42552 a tremendous tool for extreme performance environments such as the test equipment market,” he added. The PE42552 exhibits outstanding isolation of 47 dB (3.0 GHz) and approaching 30 dB at 7.5 GHz; high ESD tolerance of 1.0 kV HBM on all ports; and IIP3 of +65 dBm. The device, offered in the RoHS¬-compliant 16-lead 3 x 3 x 0.75 mm QFN package, is available for sampling in July 2008 and is priced in volume at $3.34 (100Ku).

PORTABLE DESIGN
Economy Microwave Spectrum Analyzers Anritsu Company has introduced new options for its MS271xB series that take advantage of the economy microwave spectrum analyzers’ best-in-class phase noise of -110 dBc/Hz at 10 kHz offset (typical, 800 MHz) and make it easier to integrate the instruments into legacy manufacturing environments. The MS271xB series has been designed to accurately measure the performance of wireless broadband components and devices, increase production yields, and lower the cost of production test. Running on an external PC, the software controls any of the economy microwave spectrum analyzers via an Ethernet or GPIB interface and combines multiple swept measurements into summary displays of phase noise performance. It provides multiple phase noise trace plots on the same scale, in different colors. Phase noise plots can be smoothed and compared with user-created limit lines. The software also allows source jitter measurements to be displayed in seconds, degrees, or Hz. The method in which the data is collected and displayed by the software makes it easier for wireless broadband designers and troubleshooters to predict system EVM and BER. Anritsu has also enhanced the MS271xB series with a GPIB interface, which allows the economy microwave spectrum analyzers to be easily integrated into legacy manufacturing test systems. A new front panel USB connector facilitates connection of flash drives. Covering the 9 kHz to 7.1, 13 and 20 GHz ranges, the MS271xB family meets most RF and microwave spectrum analyzer requirements. The excellent phase noise performance allows the instruments to measure most wireless local oscillators and synthesizers, while their superior dynamic range of 100 dB results in fast and precise testing of wireless components that require exceptional linearity. Designed with a 10 MHz demodulation bandwidth, the MS271xB family supports GSM, CDMA, W-CDMA, W-CDMA/ HSDPA, EVDO and WiMAX measurements, in addition to TD-SCDMA. Anritsu Company, Richardson, TX.
