HMC524LC3B v01.1106 MIXERS - I/Q MIXERS / IRM - SMT 8 GaAs MMIC I/Q MIXER 22 - 32 GHz Typical Applications Features The HMC524LC3B is ideal for: Wide IF Bandwidth: DC - 4.5 GHz • Point-to-Point Radios Image Rejection: 20 dB • Point-to-Multi-Point Radios & VSAT LO to RF Isolation: 45 dB • Test Equipment & Sensors High Input IP3: +20 dBm • Military End Use RoHS Compliant 3x3 mm SMT Package Functional Diagram General Description The HMC524LC3B is a compact I/Q MMIC mixer which can be used as either an Image Reject Mixer or a Single Sideband Upconverter. The chip utilizes standard Hittite 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 HMC524LC3B eliminates the need for wirebonding, allowing the use of surface mount techniques. Electrical Specifi cations, TA = +25° C, IF= 100 MHz, LO = +17 dBm* Parameter Min.

These pins may be connected to RF/DC ground without affecting performance 9 LO This pad is DC coupled and matched to 50 Ohms. Interface Schematic This pad 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 pad must not source/sink more than 3mA of current or die nonfunction and possible die failure will result.
