TF1003C LG1605DXB Limiting Amplifier

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 Ω 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 limitin.
