HMC-MDB218 MIXERS - SUB-HARMONIC - CHIP v00.0907 GaAs MMIC SUB-HARMONIC IRM MIXER, 54 - 64 GHz Typical Applications Features This HMC-MDB218 is ideal for: Wide IF Bandwidth: DC - 3 GHz • Short-Haul / High Capacity Radios RF Frequency: 54 to 64 GHz • SATCOM LO Frequency: 27 to 32 GHz • Military Radar, ECM & EW High Image Rejection: 30 dB • Sensors Passive; No DC Bias Required • Test & Measurement Equipment Die Size: 1.54 x 1.41 x 0.1 mm Functional Diagram General Description The HMC-MDB218 is a sub-harmonically pumped (x2) MMIC Mixer which can be used as either an image reject mixer (IRM) or a single sideband upconverter. This passive MMIC mixer is fabricated with GaAs Heterojunction Bipolar Transistor (HBT) Shottky diode technology. For downconversion applications, an external quadrature hybrid can be used to select the desired sideband while rejecting image signals. All bond pads and the die backside are Ti/Au metallized and the Shottky devices are fully passivated for reliable operation. The HMC-MDB218 Sub Harmonic IRM is compatible with conventional die attach methods, as well as thermocompression and thermosonic wire bonding, making it ideal for MCM and hybrid microcircuit applications. All data shown herein is measured with the chip in a 50 Ohm environment and contacted with RF probes. Electrical Specifi cations*, TA = 25 °C, IF = 1 GHz, LO = +10 dBm Parameter Min. Typ.

Application Circuit 2 depicts the mixer with a 90°hybrid used to achieve signal image rejection. All RF parameters are specified with an ideal 90° hybrid on IF output ports. Conversion loss is measured (on wafer) at IF1 and/or IF2 (Application Circuit 1) with the second IF port terminated into 50 ohms. Three dB is then added to compensate for an ideal hybrid. The IP3 is stated as an input IP3 number and is obtained via a two-tone measurement.
