MAPS-010144 Digital Phase Shifter Rev. V3 4-Bit, 2.3 - 3.8 GHz Features Functional Schematic 4 Bit Digital Phase Shifter 360 Coverage with LSB = 22.5 Integrated CMOS Driver Serial or Parallel Control Low DC Power Consumption Minimal Attenuation Variation over Phase Shift Range P/S 50 Impedance EAR99 Lead-Free 4 mm 24-Lead PQFN Package RoHS* Compliant Description The MAPS-010144 is a GaAs pHEMT 4-bit digital phase shifter with an integrated CMOS driver in a 4 mm PQFN plastic surface mount package. Step size is 22.5 providing phase shift from 0 to 360 in 22.5 steps. This design has been optimized to minimize variation in attenuation over the phase shift range. The MAPS-010144 is ideally suited for use where 2 high phase accuracy with minimum loss variation Pin Configuration over the phase shift range are required. The 4 mm Pin No. Function Pin No. Function PQFN package provides a smaller footprint than is typically available for a digital phase shifter with an 1 VEE 13 GND internal driver. Typical applications include 2 P/S 14 RF OUT communications antennas and phased array radars. 3 GND 15 GND 4 GND 16 GND 1 5 RF IN 17 SER OUT Ordering Information 6 GND 18 VCC Part Number Package 7 GND 19 D6 MAPS-010144-TR0500 500 piece reel 8 GND 20 D5 MAPS-010144-001SMB Sample Test Board 9 GND 21 D4 10 GND 22 D3 or LE 1.
