Product Description
The PE42427 is a HaRP™ technology-enhanced SPDT
RF switch designed to cover a broad range of
applications from 5-6000 MHz. This reflective switch
integrates on-board CMOS control logic with a low
voltage CMOS-compatible control interface and requires
no external components.
pSemi’s HaRP technology enhancements deliver high
linearity and exceptional harmonics performance. It is an
innovative feature of the UltraCMOS® process, providing
performance superior to GaAs with the economy and
integration of conventional CMOS.

Notes: 1. Typical performance over temperature and VDD shown in Figure 5 through Figure 21.
2. High frequency performance can be improved by external matching (see Figure 22 through Figure 27 and Figure 30).
3. The input P0.1dB compression point is a linearity figure of merit. Refer to Table 5 for the operating RF input power.

Switching time 50% CTRL to (10%-90%) or (90%-10%) RF 2 4 μs
Switching Frequency
The PE42427 has a maximum 25 kHz switching
frequency. Switching frequency describes the time
duration between switching events. Switching time
is the time duration between the point the control
signal reached 50% of the final value and the point
the output signal reaches within 10% or 90% of its
target value.
Spurious Performance
The PE42427 spur fundamental occurs around
13 MHz. Its typical performance is -163 dBm/Hz,
with 200 kHz bandwidth. The performance is
ideally suited for cable broadband applications.
Pin 4 should also be left unconnected for optimal
spurious performance.
Thermal Data
Psi-JT ( JT), junction top-of-package, is a thermal
metric to estimate junction temperature of a device
on the customer application PCB (JEDEC JESD51
-2).
JT = (TJ - TT)/P
where
JT = junction-to-top of package characterization
parameter, C/W
TJ = die junction temperature, C
TT = package temperature (top surface, in the
center), C
P = power dissipated by device, Watts

Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS
devices are immune to latch-up.
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 specified rating.
Moisture Sensitivity Level
The Moisture Sensitivity Level rating for the
PE42427 in the 12-lead 2 × 2 × 0.55 mm QFN
package is MSL1.
Exceeding absolute maximum ratings may cause
permanent damage. Operation should be restricted
to the limits in the Operating Ranges table.

Figure 28. Evaluation Board Layout
Evaluation Board
The SPDT switch evaluation board was designed
to ease customer evaluation of pSemi’s PE42427.
The RF common port is connected through a 50Ω
transmission line via the top SMA connector, J2.
RF1 and RF2 ports are connected through 50Ω
transmission lines via SMA connectors J1 and J3,
respectively. A through 50Ω transmission is
available via SMA connectors J4 and J5. This
transmission line can be used to estimate the loss
of the PCB over the environmental conditions
being evaluated. J8 provides DC and digital inputs
to the device.
The board is constructed of a four metal layer
material with a total thickness of 62 mils. The top
and bottom RF layers are Rogers RO4350 material
with a 10 mil RF core. The middle layers provide
ground for the transmission lines. The transmission
lines were designed using a coplanar waveguide
with ground plane model using a trace width of
22 mils, trace gaps of 7 mils, and metal thickness
of 2.1 mils.
