GENERAL DESCRIPTION
The HMC553ACHIPS is a general-purpose, double balanced,
monolithic microwave integrated circuit (MMIC) mixer that
can be used as an upconverter or a downconverter between
6 GHz and 14 GHz. This mixer is fabricated in a gallium
arsenide (GaAs), metal semiconductor field effect transistor
(MESFET) process and requires no external components or
matching circuitry.
The HMC553ACHIPS provides high local oscillator (LO) to RF
and LO to intermediate frequency (IF) suppression due to
optimized balun structures for as low as 32 dB and 28 dB,
respectively. The mixer operates with LO drive levels from
9 dBm to 15 dBm.
