Product Specification
PE42424
UltraCMOS
®
SPDT RF Switch
100 MHz–6 GHz
Product Description
The PE42424 is a HaRP™ technology-enhanced
reflective 50Ω SPDT RF switch designed for use in high
power and high performance WLAN 802.11 a/b/g/n/ac
applications such as carrier and enterprise Wi-Fi products
supporting bandwidths up to 6 GHz.
This switch features exceptional port-to-port isolation, fast
switching speed, and high power handling, all in a
compact 1.5
1.5 mm package. PE42424 also features
high linearity that remains invariant over the full power
supply range. In addition, this device has robust ESD and
temperature performance and does not require blocking
capacitors or any external matching components.
The PE42424 is manufactured on Peregrine’s
UltraCMOS
®
process, a patented variation of silicon-on-
insulator (SOI) technology on a sapphire substrate.
Peregrine’s HaRP technology enhancements deliver high
linearity and excellent harmonics performance. It is an
innovative feature of the UltraCMOS process, offering the
performance of GaAs with the economy and integration of
conventional CMOS.

Exceeding absolute maximum ratings may cause
permanent damage. Operation should be restricted
to the limits in the Operating Ranges table.
Operation between operating range maximum and
absolute maximum for extended periods may
reduce reliability.

PE42424
Product Specification
Electrostatic Discharge (ESD) Precautions
When handling this UltraCMOS device, observe
the same precautions that you would use with
other ESD-sensitive devices. Although this device
contains circuitry to protect it from damage due to
ESD, precautions should be taken to avoid
exceeding the rating specified.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS
devices are immune to latch-up.
Moisture Sensitivity Level
The Moisture Sensitivity Level rating for the
PE42424 in the 6-lead 1.5
1.5
mm DFN package
is MSL1.
Switching Capability
The PE42424 has a maximum 125 kHz switching
rate with the control pin input capacitance of 2 pF.
Switching rate describes the time duration
between switching events.
Switching time is the time duration between the
point the control signal reaches 50% of the final
value and the point the output signal reaches
within 10% or 90% of its target value.
Spurious Performance
The typical spurious performance of the PE42424
is –126 dBm.
