PE42521
UltraCMOS® SPDT RF Switch
9 kHz – 13 GHz
Product Description
The PE42521 SPDT absorptive RF switch is designed for
use in Test/ATE and other high performance wireless
applications. This broadband general purpose switch
maintains excellent RF performance and linearity from
9 kHz through 13 GHz. This switch is a pin-compatible
upgraded version of PE42552 with fast switching time and
higher power handling of 36 dBm continuous wave (CW)
and 38.5 dBm instantaneous power in 50Ω @ 4 GHz. The
PE42521 exhibits high isolation, fast settling time, and is
offered in a 3x3 mm QFN package.
The PE42521 is manufactured on Peregrine’s
UltraCMOS® process, a patented variation of silicon-oninsulator (SOI) technology on a sapphire substrate,
offering the performance of GaAs with the economy and
integration of conventional CMOS.

Switching Frequency
The PE42521 has a maximum 25 kHz switching
rate when the internal negative voltage generator
is used (pin 13 = GND). The rate at which the
PE42521 can be switched is only limited to the
switching time (Table 1) if an external negative
supply is provided (pin 13 = VssEXT).
Switching frequency 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.

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.
For proper operation, the VssEXT control pin must
be grounded or tied to the Vss voltage specified in
Table 3. When the VssEXT control pin is grounded,
FETs in the switch are biased with an internal
negative voltage generator. For applications that
require the lowest possible spur performance,
VssEXT can be applied externally to bypass the
internal negative voltage generator.
Spurious Performance
The typical spurious performance of the PE42521
is -135 dBm when VssEXT = 0V (pin 13 = GND). If
further improvement is desired, the internal
negative voltage generator can be disabled by
setting VssEXT = -3.4V.

Evaluation Kit
Figure 30. Evaluation Kit Layout
The SPDT switch evaluation board was designed
to ease customer evaluation of Peregrine’s
PE42521. The RF common port is connected
through a 50Ω transmission line via the SMA
connector, J1. RF1 and RF2 ports are connected
through 50Ω transmission lines via SMA
connectors J2 and J3, respectively. A 50Ω
through transmission line is available via SMA
connectors J5 and J6, which can be used to
de-embed the loss of the PCB. J4 provides DC
and digital inputs to the device.
For the true performance of the PE42521 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.
