DNC IR SSB Mixer used in transceiver applications

Overview

RFDN03C (DNC Mixer) is IR SSB Mixer used in transceiver application. The process used to design DNC Mixer is 0.1um GaAs pHEMT. This Mixer employs two resistive FET switches to mix LO and RF. In a resistive FET mixer, where the LO of the mixer is applied to the gate. RF is applied to the drain and consequently IF is filtered from the drain. No drain dc-bias voltage is applied to the transistor. Gate bias can help us achieve better linearity, minimum conversion loss with less LO power over the wideband down conversion operation. All results shown in datasheet with considering of parasitics and coupling effects in layout.
