HMC141C8 v04.0504 Typical Applications Features The HMC141C8 is ideal for: Input IP3: +21 dBm • Microwave Point-to-Point Radios Conversion Loss: 8.5 dB 7 • VSAT Ground Equipment LO to RF Isolation: 35 dB MIXERS - SMT GaAs MMIC SMT DOUBLEBALANCED MIXER, 6 - 15 GHz Functional Diagram General Description The HMC141C8 is a miniature passive doublebalanced mixer in a non-hermetic ceramic surface mount package that can be used as an upconverter or downconverter. The device is a passive diode/balun type mixer with high dynamic range. The mixer can handle larger signal levels than most active mixers due to the high third order intercept of 20 dBm. MMIC implementation provides exceptional balance in the circuit resulting in high LO/RF and LO/IF isolations and unit-to-unit consistency. This mixer has applications where small size and surface mount compatibility are important. Electrical Specifications, TA = +25° C, LO Drive = +15 dBm Parameter 7 - 16 Min. Typ.
