Product Overview
Mini-Circuits’ ZFLM-43-5W+ is a coaxial RF limiter ideal for protecting sensitive receiver circuitry from
high-power signals, while allowing low-scattered signals to be received. Providing input limiting range
from +10 to +37 dBm and +12 dBm output power, this model is suitable for many situations where un-
wanted signals prevail such as manufacturing sites, train tunnels, radar transceivers and more. The unit
comes housed in a rugged, aluminum alloy case (1.25” x 1.25 x 0.75”) with SMA connectors.
Key Features
Feature
Advantages
Ideal for a variety of applications requiring protection of sensitive receiver circuitry from
unwanted signals, ESD and power surges on the network.
Wideband, from 20 to 4000 MHz
Wide limiting range from
+10 to +37 dBm
Prevents a wide range of high input signal levels from passing through the network and
damaging sensitive electronic components.
Low ∆output / 1 dB ∆ input
• 0.3 dB, +10 to +20 dBm input range
• 0.1 dB, +20 to +37 dBm input range
Low delta output per 1 dB delta input maintains signal stability in the presence of volatile
input signal conditions.
Minimal downtime after unwanted signals are removed with very quick restoration of
standard operating levels.
Rapid recovery, 33ns
Low insertion loss, 0.36 dB
Low-output power, +12 dBm
Preserves the strength of low-power signals in the receive path.
Low output power prevents saturation of receiver circuitry and provides extra protection
for sensitive components.
