Richardson RFPD Inc. announces immediate availability and full design support capabilities for two newly-released additions to the family of GaAs PHEMT digital phase shifters from M/A-COM Technology Solutions Inc. The MAPS-010146and MAPS-010166 are, respectively, 4- and 6-bit packaged devices that maintain low phase error and minimal attenuation variation over the full 360-degrees and 8 to 12 GHz frequency range.

Both new devices feature a built-in CMOS driver in a 4 mm, 24-lead PQFN surface-mount package that allows for serial or parallel control and low power consumption, and both devices operate using positive and negative voltage supply. The devices are targeted for communication antennas and phased array radar applications, making them excellent candidates for commercial weather radar applications and military ground-based distance-measuring radar applications.

Key features of the 4-bit MAPS-010146 Digital Phase Shifterinclude:

• 8 to 12 GHz Frequency Range
• 6.5 dB Insertion Loss (any phase state)
• 360° Coverage with LSB = 22.5°
• Integrated CMOS Driver
• Serial or Parallel Control
• Low DC Power Consumption
• Minimal (+/- 1.0 dB) Attenuation Variation over Phase-Shift Range
• 50 Ω Impedance
• EAR99
• Lead-Free 4 mm 24-Lead PQFN Package
• RoHS* Compliant

Key features of the 6-bit MAPS-010166 Digital Phase Shifter include:

• 8 to 12 GHz Frequency Range
• 6.5 dB Insertion Loss (any phase state)
• 360° Coverage with LSB = 5.6°
• Integrated CMOS Driver
• Serial or Parallel Control
• Low DC Power Consumption
• Minimal (+/- 1.2 dB) Attenuation Variation over Phase-Shift Range
• 50 Ω Impedance
• EAR99
• Lead-Free 4 mm 24-Lead PQFN Package
• RoHS* Compliant
