The VCA2615 is a dual-channel, variable gain amplifier, combining a low-noise preamplifier (LNP) and a voltage-controlled amplifier. The VCA2615EVM evaluation module is designed to allow for a quick setup and ease of use in evaluating the performance. Various modes of operation can be configured, for example setting the LNP gain, or using the LNP outputs. The user can apply the input signal either to the LNP, or directly to the VCA section. The differential outputs of the VCA2615 are buffered using an op amp in a difference amplifier configuration.
The VCA2615EVM requires a +5V supply for the VCA itself, and +/-5V supplies for the buffer amplifiers. All signal inputs and outputs use SMA connectors
