HMC-C046 v00.0907 GaAs MMIC I/Q MIXER MODULE 20 - 31 GHz Features Wide IF Bandwidth: DC - 4.5 GHz Image Rejection: 24 dB LO to RF Isolation: 42 dB High Input IP3: 22.5 dBm Hermetically Sealed Module A li ti Typicall Applications 5 The HMC-C046 is ideal for: -55 to +85 °C Operating Temperature • Point-to-Point Radios • Point-to-Multi-Point Radios & VSAT MIXERS Field Replaceable SMA Connectors • Test Equipment & Sensors • Military End-Use Functional Diagram General Description The HMC-C046 is a passive I/Q MMIC mixer housed in a miniature hermetic module which can be used as either an Image Reject Mixer (IRM) or a Single Sideband Upconverter. The module utilizes two standard Hittite double balanced mixer cells and a 90 degree hybrid fabricated on a GaAs MESFET process. A low frequency quadrature hybrid was used to produce a 100 MHz Upper Side Band (USB) IF output. This MMIC based module is a more reliable and consistent alternative to hybrid style I/Q Mixers and Single Sideband Converter assemblies. The module features removable SMA connectors which can be detached to allow direct connection of the I/O pins to a microstrip or coplanar circuit.

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 DC coupled and matched to 50 Ohms.
