LCAT7469-9

Overview

The LCAT7469-9 is a fixed RF attenuator manufactured by L-com, designed for signal reduction in radio frequency circuits. It provides a nominal attenuation of 9 dB with a tolerance of ±1 dB across a frequency range from DC to 12 GHz. The device features a TNC connectorized design, utilizing a male plug on one end and a female jack on the other, ensuring compatibility with standard TNC interfaces. It supports a maximum continuous wave power handling of 2 Watts and maintains a maximum Voltage Standing Wave Ratio (VSWR) of 1.35:1. The unit operates within a 50 Ohm impedance system.

Feature Summary

• Fixed 9 dB attenuation value for precise signal level control
• Wideband operational capability extending from DC to 12 GHz
• Robust TNC connector interface for secure inline integration

Applications

• RF test and measurement setups requiring specific signal loss
