Limiting Amplifier with Integrated Low Pass Filter and "BIT" Circuit     

     This amplifier was designed to provide ultra-flat gain response from 5.6 to 8.4GHz.  This amplifier provides 25dB

of gain and a limited output power of 19dBm ±2dBm.  This amplifier contains integrated low-pass filters to suppress

2nd harmonics while in a limiting condition.  A BIT "TTL" circuit is incorporated on the output of the amplifier in order to

monitor the amplifiers output power level.
