VCA2612: VGA for IQ Demodulated Baseband Signal

Kazuki Itoh

Part Number: VCA2612
Other Parts Discussed in Thread: VCA2615

Hi team,

My customer is looking for VGA for baseband gain control.

Could you please help me to pick up right VGA?

HE's looking for differential I/O VGA. It needs to have continuous gain control. Gain should be from 0 - 40dB.

BB frequency is from DC - 200kHz. 2 channels are required. Is VCA2612 right part to recommend?

Thanks.

Hi Chen-san,

I found VCA2615 cannot process DC signal because it is internally AC-coupled.

What do you think?
