Description
The SKY13290-000/099 is a high power, pHEMT Single Pole
Double Throw (SPDT) switch. The switch is designed for use in
systems operating from 20 MHz to 2.5 GHz for which low loss,
high isolation, low control voltage, and chip scale size are
required.
The device is controlled with positive, negative, or a combination
of both voltages. The RF signal paths within the device are fully
bilateral.
The SKY13290-000/099
is
provided as a bare die in an ultra-
compact 1355 x 830 x 200
μm
design. Chips are shipped in
quantities of 100 per 2 x 2 inch Gel-Pak (use part number
SKY13290-000). For high volume orders, chips can be supplied on
a film frame (use part number SKY13290-099).
A functional block diagram is shown in Figure 1. The pin
configuration
is
shown in Figure 2. Signal pin assignments and
functional pin descriptions are provided in Table 1.

Technical Description
The SKY13290-000/099 is controlled using two voltage inputs, V1
and
V2
(pins 6 and 4, respectively). Depending on the voltage level
applied to these pins, the common RF port (J1) is connected to
one of two RF ports (J2 or J3) using a low insertion loss path,
while the path between J1 and the other RF port is in its isolation
state.
When the control voltages are toggled, the states between J1 and
J2, as well as J1 and J3, are also toggled.

Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value.
CAUTION:
Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
