LM2933-Q-B-301
High power, passive two-stage power limiter
The LM2933-Q-B-301 Surface Mount Silicon PIN Diode Limiter is a surface mount, passive two-stage power limiter which can operate over the frequency range of 2.9 GHz to 3.3 GHz. It is manufactured using MACOM's proven hybrid manufacturing process incorporating PIN Diodes and passive devices integrated onto a ceramic substrate. This low profile, compact, (8 mm L x 5 mm W x 2.5 mm H) surface mount component offers outstanding small and large signal performance. This product is designed for optimal small signal insertion loss for very low receiver noise figure and excellent large-input-signal flat leakage power for effective receiver protection from 2.9 GHz to 3.3 GHz. The very low thermal resistance (20 ºC/W, junction to bottom surface of package) of the PIN diodes in this device and the presence of a Schottky detector bias current source enables it to reliably handle RF incident power levels up to 47 dBm CW and RF peak incident power levels up to 62 dBm (70 µs pulse width, 3% duty cycle). The I layer thickness of the output stage and the design of the internal Schottky detector current source combine to produce flat leakage of 23 dBm typical and spike leakage energy of 0.25 ergs, typical. No external control signals are required. This limiter module includes internal DC blocking capacitors in the RF signal path, as well as an internal DC return path.
