2 GHz Ultralow Distortion Differential RF/IF Amplifier

Analog Devices 

AD8352

VS = 5 V, RL = 200 Ω differential, RG = 118 Ω (AV = 10 dB), VOUT = 2 V p-p composite, T = 25°C; parameters specified differentially, unless

otherwise noted. CD and RD are selected for differential broadband operation (see Table 6 and Table 7). See the Applications section for

single-ended to differential performance characteristics.

1 When using the evaluation board at frequencies below 50 MHz, replace the Output Balun T1 with a transformer such as Mini-Circuits ADT1-1WT to obtain the low

frequency balance required for differential HD2 cancellation.

2 CD and RD can be optimized for broadband operation below 180 MHz. For operation above 300 MHz, CD and RD components are not required.
