RFMW Ltd. announces design and sales support for a 10 MHz to 6 GHz RF power limiter capable of handling 100 W of pulsed input power. Peregrine Semiconductor’s PE45361 is a monolithic structure 8 times smaller than discrete, PIN-diode solutions and eliminates thermal hysteresis. The adjustable input 1dB compression point (limiting threshold) is set from +7 to +13dBm 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.
Fast response time of <1ns ensures instantaneous protection of sensitive components and rapid return to normal operation. Highly flexible and highly linear, the PE45361 delivers simple, repeatable, and reliable receiver protection for demanding professional mobile/portable radios, T&M equipment and wireless infrastructure applications.
Available in a 3x3mm QFN package with improved (3kV HBM) ESD ratings.
