UWB Low Noise Amplifier

Overview

The first and probably the most critical component of the analog frontend is the low noise amplifier (LNA), whose purpose is to amplify the received signal from the antenna with as little distortion and additional noise as possible. This is achieved by designing an appropriate matching network placed between the antenna and the amplifier.

UWB Passive Mixer

Overview

The current-driven passive mixer commutates only the RF current supplied by an LNA which acts as an RF transconductor. In this structure mixer switches carry no DC current, hence the ?icker noise corner is incredibly low. The mixer also exhibits good linearity (low intermodulation) and is highly capable of handling large signal swings .
