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

Operation should be restricted to the limits in the Operating Ranges table. Operation between operating range maximum and absolute maximum for extended periods may reduce reliability. 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.

Page 3 of 12 PE45140 Product Specification ESD Protection Capability Dual Mode Operation The PE45140 has the unique capability of being used as a voltage clamp in the event of an ESD strike. Clamping the output voltage can protect devices that follow from ESD damage and enable overall system ESD ratings to be increased. Power Limiting Mode The PE45140 performs as a linear power limiter with adjustable P1dB / limiting threshold. The P1dB / limiting threshold can be adjusted by changing the control voltage between -2.5V and -0.5V. If unbiased, or if VCTRL = 0V, the PE45140 still offers power limiting protection. The PE45140's ESD protection capability under biased and unbiased conditions is observed with a Transmission Line Pulse (TLP) measurement characterizing the product as an ESD clamp from each RF port to ground. Power Reflecting Mode Power reflecting mode requires a power detector to sample the RF input power and a microcontroller to toggle the limiter control voltage between +2.5V and -2.5V based on the system protection requirements. At +2.5V, the limiter impedance to ground is less than 1 and most of the incident power will be reflected back to the source. At -2.5V, the device operates as in power limiting mode. Table 5.

Table 5. Theta JC Parameter Theta JC Min Typ 16 Max Unit C/W Special consideration needs to be made in the design of the PCB to properly dissipate the heat away from the part and maintain the +270C maximum junction temperature. It is recommended to use best design practices for high power QFN packages: multi-layer PCBs with thermal vias in a thermal pad soldered to the slug of the package. Special care also needs to be made to alleviate solder voiding under the part. Document No. DOC-44014-4 www.psemi.com (c)2014 Peregrine Semiconductor Corp. All rights reserved.
