VCA2612 dual variable gain amp w. low noise preamp (X2
High Gain Adjust Range, 80 MHz
Wideband Voltage-Controlled Amplifier
The output of the LNP can be accessed externally for further signal processing, or fed directly into the VGA. The VCA2612?s VGA section consists of two parts: the Voltage Controlled Attenuator (VCA) and the Programmable Gain Amplifier (PGA). The gain and gain range of the PGA can be digitally programmed. The combination of these two programmable elements results in a variable gain ranging from 0dB up to a maximum gain as defined by the user through external connections. The output of the VGA can be used in either a single-ended or differential mode to drive high-performance Analog-to-Digital (A/D) converters.
The VCA2612 also features low crosstalk and outstanding distortion performance. The combination of low noise and gain range programmability make the VCA2612 a versatile building block in a number of applications where noise performance is critical.
* Low Input Noise: 1.25nV/ Hz
* Active Termination Noise Reduction
