The MAPS-010145 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. D3 or LE VCC (+5 V) Applications The MAPS-010145 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.

V4 Modes of Operation: Serial and Direct Parallel Mode Truth Table9,10 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. 1 X Serial 0 N/A Direct Parallel 9. 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. 10. In the parallel mode, D1 and D2 should be tied to ground or to VCC.

V4 Application Section To be complete in reviewing phase shifter performance in both directions, error metrics should be discussed. With phase shifters, both phase and amplitude error are described. Amplitude error describes the state-to-state amplitude variation. Phase error describes the delta-from ideal phase observed in each state. Amplitude error can be calculated in two ways. The first is with respect to the 0° or reference state. This can be called cross-error. Another, and perhaps more widely accepted method for calculating amplitude error, is to compare it by frequency to the mean amplitude of all the states as is calculated here. [1] Amplitude Error (dB) vs. State (S12) While the above shows amplitude error at particular frequencies vs phase shifter state, another common way to look at this parameter is error vs frequency.

V4 Application Section Phase error is calculated as the difference between the requested or ideal phase and actual insertion phase. For example, if 22.5° of shift is desired, and 23.5° is observed, the delta, or error, is 1°. Phase Error (°) vs. State (S12) Phase Error (°) vs. Frequency as shown below: Phase Error compared to ideal (S12) Following many traces, trying to consider how that will impact a system is difficult. A simpler method is adopted: RMS Error. It is important to use the right convention when applying an RMS calculation to phase shifter insertion phase. We compare the raw errors with the mean (error) below. If we use only the raw phase errors in an RMS error calculation the result will be pessimistic. This is because the average of the phase errors is not typically zero. Ignoring the mean error would result in an RMS Error that differs depending on chosen reference state.
