M/A-COM Technology Solutions has introduced a 6-bit addition to its family of digital phase shifters for communication antenna and radar applications.

The MAPS-011007 is a GaAs pHEMT 6-bit, 1.2 GHz to 1.4 GHz digital phase shifter with an integrated CMOS driver. Housed in a 4-mm 24-Lead PQFN package, the phase shifter provides 360° phase shift range with a step size of 5.6°. The package provides a smaller footprint than is typically available for a digital phase shifter with an internal driver.

The digital phase shifter is ideally suited for 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.

The GaAs pHEMT 6-bit phase shifter meets the high performance requirements of communications and radar system manufacturers, optimizing for fast switching speed, low phase error, and serial or parallel control capability. Its insertion loss is 3.8 dB, with a low 0.4 dB RMS attenuation error over the 1.2 to 1.4 GHz frequency range.

“The MAPS-011007 was specifically designed for L-band radar and communication applications,” said Kevin Harrington, Product Marketing Manager. “It’s ideal for customers looking for the lowest RMS phase and attenuation error from 1.2 GHz to 1.4 GHz.”

Other technical specifications include: attenuation variation of ±0.5 dB, RMS phase error of 2.0°, phase accuracy of ±0.4°, input IP3 of 48 dBm and 1dBcompression of 30 dBm.
