Product Specification PE45450 UltraCMOS(R) Power Limiter 9 kHz-6 GHz Product Description The PE45450 is a HaRPTM technology-enhanced power limiter designed for use in high performance power limiting applications in test and measurement equipment, radar, military electronic counter measure receivers and wireless infrastructure transceivers and antennas. Unlike traditional PIN diode solutions, the PE45450 achieves an adjustable input 1 dB compression point or limiting threshold via a low current control voltage (VCTRL), eliminating the need for external bias components, such as DC blocking capacitors, RF choke inductors, and bias resistors. It delivers low insertion loss and high linearity under nonlimiting input power levels and extremely fast response and recovery time in a limiting event. It also offers superior ESD rating and ESD protection for subsequent circuitry. The PE45450 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.

Moisture Sensitivity Level The Moisture Sensitivity Level rating for the PE45450 in the 12-lead 3x3 mm QFN package is MSL1. Document No. DOC-44314-5 www.psemi.com 1.

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. (c)2013-2014 Peregrine Semiconductor Corp.

Page 3 of 12 PE45450 Product Specification ESD Protection Capability Dual Mode Operation The PE45450 can be used as an ESD protection device to protect sensitive circuit elements against ESD surges. Besides superior ESD rating of 8 kV HBM, the PE45450 has excellent voltage clamping capability. During an ESD event, the PE45450 maintains very low voltage across the device to ensure that the circuit element it is protecting survives. Power Limiting Mode The PE45450 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 PE45450 still offers power limiting protection. 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 6. Theta JC Parameter Theta JC Min Typ 20 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 290C peak 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-44314-5 www.psemi.com (c)2013-2014 Peregrine Semiconductor Corp. All rights reserved.

Evaluation Board Layout The power limiter EVK board was designed to ease customer evaluation of Peregrine's PE45450. The bi-directional RF input and output are connected to RF1 and RF2 port through a 50 transmission line via SMA connectors J2 and J3. A through 50 transmission line is available via SMA connectors J5 and J6. This transmission line can be used to estimate the loss of the PCB over the environmental conditions being evaluated. The 2-pin connector J4 is connected to the external bias VCTRL. The board is constructed of a four metal layer material with a total thickness of 62 mils. The top RF layer is Rogers RO4350B material with a 6.6 mil RF core and Er = 3.66. The middle layers provide ground for the transmission lines. The transmission lines were designed using a coplanar waveguide with ground plane model using a trace width of 13.5 mils, trace gaps of 10 mils, and metal thickness of 2.1 mils.
