The HMC8119 is an integrated E-band gallium arsenide (GaAs) pseudomorphic (pHEMT) monolithic microwave integrated circuit (MMIC), in-phase/quadrature (I/Q) upconverter chip that operates from 81 GHz to 86 GHz. The HMC8119 provides a small signal conversion loss of 10 dB with 22 dBc of sideband rejection across the frequency band. The device uses an image rejection mixer that is driven by a 6× LO multiplier. Differential I and Q mixer inputs are provided. The inputs can be driven with differential I and Q baseband waveforms for direct conversion applications. Alternatively, the inputs can be driven using an external 90° hybrid and two external 180° hybrids for singlesideband applications. All data includes the effect of a 1 mil gold wire wedge bond on the intermediate frequency (IF) ports.
