Product Description
The PE42426 is a HaRP™ technology-enhanced reflective SPDT RF switch designed for use in land mobile
radio (LMR) and general switching applications. It delivers high linearity and excellent harmonics performance
across the entire operational band. It also features low insertion loss and high isolation performance making the
PE42426 ideal for general switching applications.
The PE42426 is manufactured on Peregrine’s UltraCMOS® process, a patented variation of silicon-on-insulator
(SOI) technology on a sapphire substrate, of fering the perf ormance of GaAs with th e economy and integration of
conventional CMOS.

Absolute Maximum Ratings
Exceeding absolute maximum ratings listed in Table 1 may cause permanent damage. Operation should be
restricted to the limits in Table 2. Operation between operating range maximum and absolute maximum for
extended periods may reduce reliability.
ESD Precautions
When handling this UltraCMOS device, observe the same precautions as with any 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 in Table 1.
Latch-up Immunity
Unlike conventional CMOS devices, UltraCMOS devices are immune to latch-up.

Switching Frequency
The PE42426 has a maximum 10 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 PE42426 spur fundamental occurs around
10 MHz. Its typical performance is –154 dBm/Hz
(V1 = H) and –165 dBm/Hz (V1 = L), with 100 kHz
bandwidth.
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

Evaluation Kit
The PE42426 evaluation board was designed to ease customer evaluation of the PE42426 RF switch. The RF
common port is connected through a 50Ω transmission line via J3. RF1 and RF2 ports are connected through
50Ω transmission lines via J1 and J2, respectively. A 50Ω through transmission line is available via J4 (THRU
left) and J5 (THRU rig ht), which can be used to de- embed the loss of the PC B. J6 provide s DC and digital inputs
to the device.
