Product Specification PE45140 UltraCMOS Power Limiter 20 MHz2 GHz Product Description The PE45140 is a HaRP technology-enhanced RF Features power limiter designed for use in tactical and military Monolithic drop in solution with no communications receivers, land mobile radio and other external components required high performance power limiting applications. Adjustable power limiting threshold Unlike traditional PIN diode solutions the limiting from +22 dBm to +32 dBm threshold can be adjusted through a low current control Max power handling voltage (V ), eliminating the need for external CTRL +47 dBm Pulsed (50W) components such as DC blocking capacitors, RF choke inductors, and bias resistors. +40 dBm CW (10W) Superior ESD rating and ESD protection This power limiter has symmetric RF ports that limit 8 kV HBM on RF pins to GND incident power up to 50W pulsed in both biased and 1 kV CDM on all pins unbiased conditions. It provides an extremely fast limiting response to undesired high power signals while delivering 200V MM on all pins low insertion loss and high linearity under safe operating Unbiased power limiting operation power levels. Fast response and recovery time of 1 ns The PE45140 is manufactured on Peregrines Dual mode operation UltraCMOS process, a patented variation of silicon-on- Power limiting mode insulator (SOI) technology on a sapphire substrate. Power reflecting mode Peregrines HaRP technology enhancements deliver high linearity and excellent harmonics performance. It is an innovative feature of the UltraCMOS process, offering the performance of GaAs with the economy and Figure 2. Package Type 12-lead 3x3 mm QFN integration of conventional CMOS. Figure 1.

Measured with +40 dBm CW applied at input. 2. This mode requires the control voltage to toggle between +2.5V and -2.5V. At +2.5V, the limiter equivalent circuit is a low impedance to ground, reflecting most of the incident power back to the source. 3. State change is V toggle from 2.5V to +2.5V.
