Control Devices: MLP 7100 Series
Limiter Diodes
Description
The MicroMetrics MLP 7100 series
Limiter diodes are specially processed
PIN diodes with a thin intrinsic region
designed for use in passive or active
limiters over the entire range of fre-
quencies from 100 MHz to beyond 20
GHz. The different “I” region thick-
nesses and capacitances provide vari-
able threshold and leakage power lev-
els and power handling capability.
Applications
The MLP 7100 series limiters are for
use in waveguides, coax, microstrip or
stripline. Single or cascade devices
may be used depending on power
levels.

Notes:
1. Pulsed thermal impedance is given for a 1 µs pulse. CW thermal impedance presumes infinite heat sink.
2. Threshold input power produces 1 dB increase in insertion loss. Figure shows typical leakage power curves. Data taken
for 1.0 GHz.
3. Chip loss can be represented as a resistance in shunt with the junction capacitance. Rpis measured at 3 GHz, zero
Bias. Loss data shown are for 10 GHz for 0.15 and 0.30 pF chips, 5 GHz for 0.50 pF chips. Loss is measured at -10
dBm input.
4. Note that CW power and average power are not synonymous. Power ratings are computed in terms of a peak
junction temperature of 200°C, for short pulses, an average junction temperature of 125°C, and an ambient of 25°C.
Duty factor 0.001 assumed for maximum pulse power input. Figure shows power derating with temperature.
5. Recovery time is measured with ground return (less than 1.0 Ohm) to 1 dB excess loss, at 1 GHz.
6. Series resistance is measured at 500 MHz.
7. Limiter diodes with higher capacitance and/or higher breakdown voltage for very high power applications are
available on request.
