RF limiters are passive low cost integrated circuits used to protect expensive, power sensitive front-end components such as amplifiers and high frequency ADCs.
Marki Microwave’s DLM series limiters feature a tuneable bias voltage which adjusts the maximum power allowed to be output from the limiter, and are suitable for low power applications such as ADC interfaces.
Marki’s HLM series are fixed limiters that handle much higher input powers and are optimized to provide high linearity.
Currently the DLM series are available in a QFN package or evaluation module, and the HLM series are available as bare die or connectorized module.
