Description
The M/A-COM MAMUSM0008 is a 0 to 750 pS variable
delay line controlled by 4 complementary bit pairs. It
provides the user with 50 pS delay step sizes for use in
standard wireless applications. The MAMUSM0008 is
particularly useful in providing time delay in the
cancellation loops of feed-forward amplifiers.

Herein is described the control method for the
MAMUSM0008 Digital Delay Line. The information will
be aimed specifically at the use of the delay line mounted
on a M/A-COM test sample board. The same theory and
control scheme can be applied directly to the component by
itself.

This product allows the insertion of a variable electrical
delay between its two ports. The control consists of four
complimentary bit pairs (8 bits total). Each pair is given a
different letter, as shown in the table to the right:
Note that each delay line has a pair named as follows:
CTL_A1 and CTL_A2, CTL_B1 and CTL_B2,
CTL_C1 and CTL_C2, CTL_D1 and CTL_D2.

The above table illustrates the method of controlling the bits for the desired delay in pico seconds. The hex and decimal
representations are included for programming purposes. “1” denotes 5 volts and “0” denotes 0 volts. A given delay line is set
when bits 2 and bit 1 are set to 0 and 1 respectively. The given delay line is bypassed when the bits 2 and 1 are set to 1 and 0
respectively.
The “GND” pin on the test board header must be connected to the DC supply ground.

Measurement
MAMUSM0008
V 1.00
Ordering Information
The simplest way to measure the delay steps is with a vec-
tor network analyzer (VNA). For taking S-Parameter
data, perform a standard calibration and measure the pa-
rameters for the given state.

Below is a description of how to see the delay accurately.
M/A-COM recommends the following measurement pro-
cedure:
Units Mounted on Test Board
Set the delay line to the reference or insertion delay state.
With the two ports of the VNA connected to the “in” and
“out” on the test board, measuring S21, set displayà
memory, and display data/memory. This will normalize
your data to the reference insertion state.
Next, switch the measurement format to phase. This
should be flat and zero due to the normalization. Switch
in the first delay line. (50ps). The display will not remain
on zero, but will have an offset. Under the Scale/
Reference menu, select electrical delay, and dial that up
until the data reads zero again, across the band of interest.
That electrical delay will be 50ps.
Continue to switch in the delay lines, dialing in more
delay each time.
Other methods are possible, but this is the most straight-
forward approach. We do not recommend using the
‘delay’ format in the VNA. The VNA’s method of
measuring this results in a noisy response, and is less
accurate than the method outlined above.
Upon request, M/A-COM can provide a test control board
to ease stepping through the states.
