The PE42556 RF switch is designed for use in Test/ATE,
cellular and other wireless applications. This broadband
general purpose switch maintains excellent RF
performance and linearity from 9 kHz through
13500 MHz. The PE42556 integrates on-board CMOS
control logic driven by a single-pin, low voltage CMOS
control input. It also has a logic select pin which enables
changing the logic definition of the control pin. Additional
features include a novel user defined logic table, enabled
by the on-board CMOS circuitry. The PE42556 also
exhibits excellent isolation of 26 dB at 13500 MHz, fast
settling time, and is offered in a tiny Flip Chip package.
The PE42556 is manufactured on Peregrine’s
UltraCMOS® process, a patented variation of silicon-on-
insulator (SOI) technology on a sapphire substrate,
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.

the limits in the Operating Ranges table. Operation
between operating range maximum and absolute

Switching Frequency
The PE42556 has a maximum 25 kHz switching rate
when the internal negative voltage generator is used
(bump1 = GND). The rate at which the PE42556 can
be switched is only limited to the switching time
(Table 1) if an external negative supply is provided
(bump1 = VSS).
Spurious Performance
The typical spurious performance of the PE42556 is
-116 dBm when VSS = 0V (bump 1 = GND). If further
improvement is desired, the internal negative voltage
generator can be disabled by setting VSS = -VDD.
Note: 4. Please consult Figures 4 and 5 (low-frequency graphs) for recommended
low-frequency operating power level.

Figure 5 shows how the power limit in Figure 4 will

increases, the contours and Maximum Power

vs. Vdd and Input Power @ 9 kHz
Figure 5. Operating Power Offset vs.

Figure 4 provides guidelines of how to adjust the
Vdd and Input Power to the PE42556 device. The
upper limit curve represents the maximum Input
Power vs Vdd recommended for this part at low
frequencies only. Please consult Table 3 for the
1 MHz 13.5 GHz range.
To allow for sustained operation under any load VSWR condition, max power
should be kept 6dB lower than max power in 50 Ohm.
Power Handling Examples
Example 1: Maximum power handling at 100 kHz,
Z = 50 ohms, VSWR 1:1, and Vdd = 3V
 The power handling offset for 100 kHz from
Fig. 5 is 7 dB
 The max power handling at Vdd = 3V is 5.5 dB
from Fig. 4
 Derate power under mismatch conditions
 Total maximum power handling for this
example is 7 dB + 5.5 dB = 12.5 dBm
Low Frequency Power Handling: ZL = 50

Figure 7. Evaluation Board Schematic
Peregrine Specification 102/0478
The SPDT switch EK Board was designed to ease
customer evaluation of Peregrine's PE42556 (dual
use with PE42554). The RF Common port is
connected through a 50 ohm transmission line via
the top SMA connector, J1. RF1 and RF2 are
connected through 50 ohm transmission lines via
SMA connectors J3, and J2, respectively. A
through 50 ohm transmission line 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.
The board is constructed of a four metal layers
with a total thickness of 62 mils. The top and
bottom layers are ROGERS RO4003 material with
an 8 mil core and Er = 3.55. The middle layers
provide ground for the transmission lines. The RF
transmission lines were designed using a coplanar
waveguide with ground plane model using a trace
width of 15 mils, and trace gaps of 10 mils.
