Product Detail

LM501202-L-C-300
Octave Band, Low Power
The LM501202-L-C-300 Surface Mount Silicon PIN Diode Limiter is a surface mount, passive two-stage power limiter which can operate over the frequency range of 400 MHz to 2.5 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 400 MHz to 2.5 GHz. The very low thermal resistance (< 70 ºC/W ) of the PIN diodes in this device enables it to reliably handle RF incident power levels up to 37 dBm CW and RF peak incident power levels up to 51 dBm (1 µs pulse width, 0.1% duty cycle) at TA = 85 ºC. The I layer thickness of the output stage is selected to produce flat leakage of 21 dBm typical and spike leakage energy of 0.2 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. The LM501202-L-C-300 limiter is ideal for receiver protection in octave band radar applications in the 400 MHz to 2.5 GHz range which utilize high volume, surface mount, solder re-flow manufacturing. These products are durable and capable of reliably operating in military, commercial, and industrial environments The devices are RoHS compliant and are available in tube or tape-reel.
