- | The Receiver block is designed to take a received signal from the 4 external antennae as well as an LO signal from teh Multiplier block, amplify and convert the received signal to an IF using all four LNA/Mixer channels, and scale the output signal using four independently controlled IF amplifiers. To accomplish this, the Receiver block contains four Low Noise Amplifiers (LNAs), four active mixers, two stages of active LO splitters and four Variable Gain Amplifiers (VGAs). It should be noted that all four channels are intended to be operated together, but any combination of channels can be enabled at once. | + | The Receiver block is designed to take a received signal from the 4 external antennae as well as an LO signal from the Multiplier block, amplify and convert the received signal to an IF using all four LNA/Mixer channels, and scale the output signal using four independently controlled IF amplifiers.
