PE45140 Datasheet, PDF (1/12 Pages) Peregrine Semiconductor – UltraCMOS® Power Limiter 20 MHz–2 GHz
Preliminary Specification
PE45140
UltraCMOS® Power Limiter
Product Description
The PE45140 is a HaRP™ technology-enhanced RF
n power limiter designed for use in tactical and military
communications receivers, land mobile radio and other
io high performance power limiting applications.
This power limiter has symmetric RF ports that limit
t incident power up to 50W pulsed in both biased and
a unbiased conditions. It provides an extremely fast limiting
response to undesired high power signals while delivering
ic low insertion loss and high linearity under safe operating
power levels.
if Unlike traditional PIN diode solutions the limiting
threshold can be adjusted through a low current control
c voltage (VCTRL), eliminating the need for external
components such as DC blocking capacitors, RF choke
e inductors, and bias resistors.
p The PE45140 is manufactured on Peregrine’s
UltraCMOS® process, a patented variation of silicon-on-
insulator (SOI) technology on a sapphire substrate.
S Peregrine’s HaRP™ technology enhancements deliver
high linearity and excellent harmonics performance. It is
y an innovative feature of the UltraCMOS process, offering
r the performance of GaAs with the economy and
integration of conventional CMOS.
