GENERAL DESCRIPTION
The HMC774A is a general-purpose, gallium arsenide (GaAs),
monolithic microwave integrated circuit (MMIC), double
balanced mixer chip that can be used as an upconverter or
downconverter from 7 GHz to 40 GHz. This mixer requires
no external components or matching circuitry.
The HMC774A provides excellent local oscillator (LO) to
radio frequency (RF) and LO to intermediate frequency (IF)
suppression due to optimized balun structures. The mixer
operates well with LO drive levels of 13 dBm. The HMC774A
is also available in surface-mount technology format as the
HMC774ALC3B.
