Description
The MAPS-010146 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-010146 is ideally suited for use where
high phase accuracy with minimum loss variation
over the phase shift range are required. The 4 mm
PQFN package provides a smaller footprint than is
typically available for a digital phase shifter with an
internal driver. Typical applications include
communications antennas and phased array radars.

Digital Phase Shifter
4-Bit, 8.0 - 12.0 GHz
Rev. V3
Modes of Operation:
Serial and Direct Parallel
Serial Mode
The serial control interface (SERIN, CLK, LE,
SEROUT) is compatible with the SPI protocol. SPI
mode is activated when P/S is kept high. The 6-bit
serial word must be loaded with the MSB first. After
shifting in the 6 bit word, a rising edge on LE will set
the phase shifter to the desired state. While LE is
high the CLK is masked to protect the data while
implementing the change. SEROUT is SERIN
delayed by 6 clock cycles.
When P/S is low, the serial control interface is
disabled. When P/S is set high, Pins 22, 23, and 24
have the LE, CLK, and SER IN function.
In serial mode operation, the outputs will stay
constant while LE is kept low.
Direct Parallel Mode
The parallel mode is enabled when P/S is set low. In
the direct parallel mode, the phase shifter is
controlled by the parallel control inputs directly.
When P/S is set low, Pins 22, 23, and 24 have the
D3, D2, and D1 function.

8. There are two dummy bits (D1 & D2), that must be sent in the
serial mode. This is because the 4 bit phase shifter uses the
same driver as the 6 bit phase shifter.
9. In the parallel mode, D1 and D2 should be tied to ground or to
VCC.
