Product Description
The PE42552 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 DC through 7500 MHz. The PE42552 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 PE42552 also exhibits
outstanding isolation of 44 dB at 7500 MHz, fast settling time,
and is offered in a tiny 3x3 mm QFN package.
The PE42552 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.

Evaluation Kit
The SPDT switch EK Board was designed to ease
customer evaluation of Peregrine’s PE42552. The
RF common port is connected through a 50
transmission line via the top SMA connector, J1.
RF1, RF2, RF3 and RF4 are connected through
50 transmission lines via SMA connectors J3,
J5, J2 and J4, respectively. A through 50
transmission is available via SMA connectors J6
and J7. This transmission line can be used to
estimate the loss of the PCB over the
environmental conditions being evaluated.
The evaluation kit board is constructed of four
metal layers. The dual clad top RF layer is
Rogers RO4003 material with an 8 mil RF core
and er = 3.55. The other two dielectric layers are
FR4 for DC control and overall board strength with
an cumulative board thickness of 60 mils. The RF
transmission lines were designed using a
Grounded co-planar waveguide with a linewidth of
15 mils and gap of 10 mils.
