Six-bit digital phase shifter for communications antenna and radar introduced by M/A-COM

LOWELL, Mass., 19 June 2012. M/A-COM Technology Solutions Inc. in Lowell, Mass., is introducing the MAPS-011007 six-bit digital phase shifter for RF and microwave applications such as communications antennas and radar.

The MAPS-011007 is a gallium arsenide (GaAs) pseudomorphic high electron mobility transistor (pHEMT) 1.2-to-1.4 GHz digital phase shifter with an integrated complementary metal oxide silicon (CMOS) driver (story continues below).

Housed in a 4-millimeter 24-lead power quad flat pack no-lead (PQFN) package, the phase shifter provides 360-degree phase shift range with a step size of 5.6 degrees. The package provides a smaller footprint than is typically available for a digital phase shifter with an internal driver, company officials say.

The MAPS-011007 is for applications where high phase accuracy with minimum loss variation is necessary. The design has been optimized to variation in attenuation to a minimum over the phase shift range.

The device meets the requirements of communications and radar system manufacturers, optimizing for fast switching speed, low phase error, and serial or parallel control capability, company officials say. Its insertion loss is 3.8 decibels, with a low 0.4-decibel RMS attenuation error over the 1.2 to 1.4 GHz frequency range.
