Functional Description

The LG1605DXB is a GaAs wideband limiting amplifier with differential inputs and outputs that provides 28 dB of gain (34 dB differential) and 3 GHz of bandwidth in a 50 ? environment (Figure 1 shows the block diagram). At low input levels, below 10 mV to 20 mV, the circuit behaves as a linear amplifier. At higher levels, the device goes smoothly into limiting. The device matches the performance of an AGC amplifier but shows none of the AGC bouncing and attack characteristics.
