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.

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.

Evaluation Kit
The SPDT switch evaluation board was designed
to ease customer evaluation of Peregrine’s
PE42424 RF switch. The RF common port is
connected to the device through a 50Ω
transmission line via SMA connector J3. RF1 and
RF2 ports are connected to the device through
50Ω transmission lines via SMA connectors J1
and J2, respectively. A transmission line has been
included on the reverse side of the PCB,
accessible via SMA connectors J4 and J5. This
transmission line provides an equivalent length to
de-embed PCB trace losses. DC and digital inputs
are provided to the device via J6.
This PCB is constructed of a four metal layer
material with total thickness of 62 mils. The top
and bottom RF layers are Rogers RO4003
material with an 8 mil RF core. The middle layers
provide ground for the RF transmission lines. The
transmission lines were designed using a coplanar
waveguide with ground plane model using a trace
width of 16 mils and 10 mil trace gap, with 2.1 mils
of metal thickness.
For the true performance of the PE42424 to be
realized, the PCB should be designed in such a
way that RF transmission lines and sensitive DC
I/O traces are heavily isolated from one another.
