M/A-COM Technology Solutions Inc of Lowell,MA,USA(which makes analog semiconductors,components and subassemblies for RF,microwave and millimeter-wave applications)has launched a 6-bit addition to its family of digital phase shifters for communication antenna and radar applications.
The MAPS-011007 is a gallium arsenide(GaAs)pseudomorphic high-electron-mobility transistor(pHEMT)6-bit 1.2-1.4GHz digital phase shifter(with an integrated CMOS driver)that provides 360°phase-shift range with a step size of 5.6°.Housed in a 4mm 24-lead PQFN package,the footprint is smaller than is typically available for a digital phase shifter with an internal driver,the firm claims.
M/A-COM Tech says that the MAPS-011007 is suited to applications where high phase accuracy with minimum loss variation is required.The design has been optimized to minimize variation in attenuation over the phase-shift range,and facilitates easy implementation,it adds.
The firm claims that the GaAs pHEMT 6-bit phase shifter meets the performance requirements of communications and radar system manufacturers,optimizing for fast switching speed,low phase error,and serial or parallel control capability.Insertion loss is 3.8dB,with a low 0.4dB RMS attenuation error over the 1.2-1.4GHz frequency range.
"The MAPS-011007 was specifically designed for L-band radar and communication applications,"says product marketing manager Kevin Harrington."It's ideal for customers looking for the lowest RMS phase and attenuation error from 1.2GHz to 1.4GHz."
