Description
The LM102202-Q-C-301 Surface Mount Silicon PIN Diode Limiter 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.
Using PIN Diodes with lower thermal resistance ( < 15 ºC/W ), and a de-coupled Schottky detector network
as a current source, RF C.W. incident power levels of +50 dBm and RF peak incident power levels of
+60 dBm @ 25 μS RF pulse width, 5% duty cycle are very achievable. In addition, this design concept
provides lower flat leakage power ( < +17 dBm ) and lower spike leakage energy ( < 0.5 Ergs ) for superior
LNA protection. The LM102202-Q-C-301 limiter can be configured without a D.C. block on the output to
obtain lower flat leakage power, (< +10 dBm) with an external ZBD schottky diode. This Limiter Part Number
is LM102202-Q-B-301. Schottky diode P/N in surface mount, 3 terminal plastic package is MZB601-2012.
Applications
These LM102202-Q-C-301 and LM102202-Q-B-301 Limiters are ideal for octave band Radar applications,
from 1-2 GHz, 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 LM102202-Q-C-301 and LM102202-Q-B-301 Limiters are capable of meeting the environmental
requirements of MIL-STD-750 and MIL-STD-202.
ESD and Moisture Sensitivity Level Rating
PIN Diode Limiters are susceptible to ESD conditions as with all semiconductors. The ESD rating for this
device is Class 0, HBM. The moisture sensitivity level rating for this device is MSL 2.
