HEROTEK LS1118 PIN Diode Limiter | 11–18GHz RF Receiver Protection
HEROTEK LS1118 is a high-performance PIN diode RF limiter designed for microwave receiver protection in the Ku-band (11–18 GHz). It is widely used to safeguard sensitive front-end components such as LNAs from damage caused by high-power RF signals.

Key Features
Frequency Range: 11 – 18 GHz
Limiter Type: Passive PIN diode limiter (detector activated)
Low Insertion Loss: Typically around 2 dB
Effective Receiver Protection: Limits output leakage to protect sensitive RF components
High Power Handling: Supports high peak input power for pulsed applications
No External Bias Required: Simple and reliable system integration
Wide Operating Temperature Range: Suitable for harsh environments
Typical Applications
Microwave and RF receiver front-end protection
LNA protection in radar and EW systems
Satellite communication systems
Microwave instrumentation and test equipment
