PIN DIODE FEEDBACK LIMITERS
Feedback limiters are designed to have lower threshold and leakage levels than
those of conventional limiters in order to protect more sensitive components.
They incorporate input PIN diode limiters which are driven by one or more
schottky detector diodes. Most circuits include DC blocks, which are required
for proper operation.
In some very low frequency models, it is not possible to include DC blocks. The
application must be such that no low impedance DC path from the center
conductor to ground exists outside the unit. The limiter threshold (1dB
compression) is typically +5dBm.
Feedback limiters will also handle peak power levels above 100W (1usec pulse
width, 0.001 duty cycle, and 1kHz repetition rate). Peak leakages are higher
than CW leakages as they are with conventional limiters. This becomes
exaggerated at frequencies below 2GHz.

NOTES:
1) CW leakage is measured at 1W input.
2) Higher power handling available. Contact the factory to discuss specific requirements.
3) Power handling is linearly derated from full power at +25°C to zero power at +150°C.
