Microwave Limiting Amplifier
8 to 12 GHz
Model BXL9812
• Reverse Bias Protection
• Input Voltage Regulator
• Laser Sealed Housing
The Model BXL9812 is standard high frequency limiting amplifier covering 8 GHz to 12 GHz. This two stage design, utilizes
an input voltage regulator to protect against fluctuations in supply voltage, reverse bias protection circuitry, and a laser
sealed housing for the ultimate in environmental protection. This standard design may also be ordered in a screened MILSTD-883 version as a model SXL9812. All specification ratings are based on measurements in a 50 ohm system with a DC
supply voltage tolerance of +/- 2%.
