Description
The SKY19001-001 is a shunt Single-Pole, Single-Throw (SPST)
switch with an integrated logic and bias block. The device
achieves high linearity and high voltage handling using a 2.85 V
typical supply.
The logic block operates with a 1.8 V high control voltage. The
ultra-low “on” resistance (R
ON
) enables high-Q antenna aperture
tuning and other low-loss tunable matches.
The linearity and voltage handling under high VSWR conditions,
and low voltage supply makes the SKY19001-001 an ideal choice
for antenna tuning applications.
The SKY19001-001 is provided in a compact 10-bump, 1.2 x 1.6
mm Wafer Level Chip Scale Package (WLCSP) that meets
requirements for board-level assembly.
A functional block diagram is shown in Figure 1. The pin
configuration and package are shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in
Table 1.

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. Exceeding any of the limits listed here may result in permanent damage to the device.
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.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY19001-001 are provided
in Table 2. Electrical specifications are provided in Tables 3 and 4.
Harmonic measurement frequencies are listed in Table 5. The
state of the SKY19001-001 is determined by the logic provided in
Table 6.
