MACOM LM401102-Q-C-301-T

LM401102-Q-x-301 is a surface-mount passive two-stage power limiter operating across a frequency range of 400 to 1000 MHz. It utilizes a proven hybrid manufacturing process that integrates PIN diodes and passive components onto a ceramic substrate. This low-profile, compact surface-mount assembly delivers excellent small-signal and large-signal performance. LM401102-Q-A-301 includes a "coarse limiting stage" of shunt PIN limiter diodes driven by a Schottky diode detector stage, and a "cleanup stage" limiter PIN diode with an internal RF choke DC return. LM401102-Q-B-301 includes a DC blocking capacitor at its input, a "coarse limiting stage" of shunt PIN limiter diodes driven by a Schottky diode detector stage, and a "cleanup stage" limiter PIN diode with an internal RF choke DC return. LM401102-Q-C-301 includes a DC blocking capacitor at its input, shunt PIN limiter diodes driven by a Schottky diode detector stage, a "cleanup stage" limiter PIN diode with an internal RF choke DC return, and a DC blocking capacitor at its output. The extremely low thermal resistance of the PIN diodes within the device (15°C/W, junction to package bottom) combined with the presence of the Schottky detector bias current source enables reliable handling of RF incident power levels up to 50 dBm CW and up to 60 dBm peak (25 μs pulse width, 5% duty cycle) at TCASE = 85°C. The combination of the output stage I-layer thickness and the internal Schottky detector current source design yields a typical flat leakage of 18 dBm and a typical spike leakage energy of 0.5 ergs. No external control signals are required. These devices are ideally suited for active receiver protection applications.
