PE45450 Datasheet, PDF (1/12 Pages) Peregrine Semiconductor – UltraCMOS® Power Limiter

Preliminary Specification
PE45450
Product Description
n ^{The PE45450 is a HaRP™ technology-enhanced power}
limiter designed for use in high performance power
limiting applications in test and measurement equipment,
io ^{radar, military electronic counter measure receivers and}
wireless infrastructure transceivers and antennas.
t _{Unlike traditional PIN diode solutions, the PE45450}
a _{achieves an adjustable input 1 dB compression point or}
limiting threshold via a low current control voltage (V_CTRL),
ic ^{eliminating the need for external bias components, such}
as DC blocking capacitors, RF choke inductors, and bias
if ^{resistors. It delivers low insertion loss and high linearity}
under non-limiting input power levels and extremely fast
response and recovery time in a limiting event. It also
c ^{offers superior ESD rating and ESD protection for}
subsequent circuitry.
e _{The PE45450 is manufactured on Peregrine’s}
UltraCMOS^® process, a patented variation of silicon-on-
p _{insulator (SOI) technology on a sapphire substrate,}
offering excellent RF performance.
S _{Peregrine’s HaRP™ technology enhancements deliver}
high linearity and excellent harmonics performance. It is
y an innovative feature of the UltraCMOS process, offering
the performance of GaAs with the economy and
r _{integration of conventional CMOS.}
