Waveplate Configuration
The following figure shows a device cross section and a possible orientation of the five waveplates with respect
to
:
Figure 1. Waveplate Configuration
To get a quarter waveplate oriented at
, the voltages applied to the device are as follows:
V1 = Vdc(90) + Vdc(0) + Vac(0)
cos(2
) + Vac(90)
sin(2
)
V2 = Vdc(90) Vdc(0) + Vac(0)
cos(2
) Vac(90)
sin(2
)
where Vdc(0), Vdc(90), Vac(0), and Vac(90) are the four characteristic voltages of each waveplate.
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.

Electrostatic Discharge
CAUTION: This device is susceptible to damage as a result of electrostatic discharge. Take proper precau-
tions during both handling and testing. Follow guidelines such as JEDEC Publication No. 108-A
(Dec. 1988).
TriQuint Semiconductor employs a human-body model (HBM) for ESD-susceptibility testing and protection-design
evaluation. ESD voltage thresholds are dependent on the critical parameters used to define the model. A standard
HBM (resistance = 1.5 k
, capacitance = 100 pF) is widely used and can be used for comparison purposes.
Package Information
Designed to NEBS (inside plant) standards, the hermetic package design incorporates a laser-sealed lid and sol-
dered fibers. The minimum bend radius for the fiber is 1.5 in.
