document no. ds12635, rev. a revision date: 6/3/09 surface mount pin diode limiters mlm2060-300 & mlm2060-301 series datasheet description the mlm2060-300 and mlm2060-301 series of surface mount silicon pin diode limiters is manufactured using aeroflex-metelics proven hybrid manufacturing process incorporating pin diodes and passive devices integrated within a ceramic substrate. this low profile, compact , surface mount component, ( 8mm l x 5mm w x 2.5 mm h ) offers superior low and high signal performance to comparable mmic devices in qfn packages. the limiter modules are designed to optimize small signal insertion loss, ( n.f.) and high signal flat leakage performance in a compact, surface mount package. the mlm2060-300 has shunt pin limiter diodes and a shunt coil with no d.c. blocks, whereas the mlm2060-301 incorporates shunt pin limiters diodes, a shunt coil, and d.c. blocks for versatility of design preference. using pin diodes with lower thermal resistance ( < 40 oc/w ), rf c.w. incident power levels of +36 dbm and rf peak incident power levels of + 50 dbm @ 1 s rf pulse width, 0.001 duty cycle are very achievable in broadband limiter applications. the lower pin diode series resistance, ( < 1.5 ), coupled with the smaller minority carrier lifetime, ( < 20 s ), provides lower flat leakage power ( < + 20 dbm ) and lower spike leakage energy ( < 0.1 ergs ) for superior lna protection. applications these mlm2060-300 and mlm2060-301 limiter series are ideal for 2 to 6 ghz radar, ied, and wimax applications, requiring high volume, surface mount, solder re-flow manufacturing. these products are durable, reliable, and capable of meeting all military, commercial, and industrial environments. the devices are fully rohs compliant and are available in tube or tape-reel. environmental capabilities the mlm2060-300 and mlm2060-301 limiter series is capable of meeting the environmental requirements of mil-std-750, mil-std-202, and mil-std-883. esd rating pin diodes are susceptible to esd conditions as with all semiconductors. the esd rating for these devices is class 0, hbm. features ? surface mount limiter in compact outline: 8mm l x 5mm w x 2.5 mm h ? incorporates pin limiter diodes, d.c. blocks & d.c. return ? higher average power handling than plastic ( 100 w peak power ) ? lower insertion loss ( 0.85 db ) & lower flat leakage power ( 19 dbm ) ? rohs compliant
