HMC521LC4

HMC521LC4 v00.0105 GaAs MMIC I/Q MIXER 8.5 - 13.5 GHz Typical Applications The HMC521LC4 is ideal for: • Point-to-Point and Point-to-Multi-Point Radio Features Wide IF Bandwidth: DC - 3.5 GHz Image Rejection: 38 dB LO to RF Isolation: 50 dB High Input IP3: +23 dBm RoHS Compliant 4x4 mm SMT Package 7 MIXERS - SMT • Military Radar Functional Diagram General Description The HMC521LC4 is a compact I /Q MMIC mixer in a leadless “Pb free” RoHS compliant SMT package, which can be used as either an Image Reject Mixer or a Single Sideband Upconverter. The mixer utilizes two standard Hittite double balanced mixer cells and a 90 degree hybrid fabricated in a GaAs MESFET process. A low frequency quadrature hybrid was used to produce a 100 MHz USB IF output. This product is a much smaller alternative to hybrid style Image Reject Mixers and Single Sideband Upconverter assemblies. The HMC521LC4 eliminates the need for wire bonding allowing use of surface mount manufacturing techniques.

These pins may be connected to RF/DC ground without affecting performance. These pins and package bottom must be connected to RF/DC ground. This pin is AC coupled and matched to 50 Ohms from 8.5 to 13.5 GHz. This pin is DC coupled. For applications not requiring operation to DC, this port should be DC blocked externally using a series capacitor whose value has been chosen to pass the necessary IF frequency range. For operation to DC, this pin must not source/sink more than 3mA of current or part non-function and possible part failure will result. This pin is AC coupled and matched to 50 Ohms from 8.5 to 13.5 GHz.
