600 MHz variable gain amplifier for IF/baseband chains
This part is designed for automatic gain control (AGC) loops in intermediate-frequency (IF) and baseband receiver paths, where the combination of wide bandwidth and gain adjustability lets the system maintain a constant signal level into an ADC or demodulator. The differential output simplifies driving differential-input ADCs without an extra balun or transformer stage.
The 107 mA supply current is moderate — budget it in a multi-channel receiver card where several such amplifiers share a regulator.
