MICROWAVE CORPORATION HMC351S8 v02.1001 GaAs MMIC HIGH IP3 DOUBLEBALANCED MIXER, 0.7 - 1.2 GHz Typical Applications Features The HMC351S8 is ideal for: Conversion Loss: 9.0 dB • Cellular Basestations LO/IF Isolation: 35 dB • Cable Modems LO/RF Isolation: 42 dB • Fixed Wireless Access Systems Input IP3: +25 dBm Input IP2: +48 dBm Functional Diagram The HMC351S8 is a double balanced mixer in an 8 lead plastic surface mount package. The passive GaAs schottky diode mixer implements planar on chip baluns and requires no external components. The mixer can be used as an upconverter, down converter, or modulator. The mixer provides 9 dB conversion loss and +25 dBm IIP3 with LO drive levels of +19 dBm. The design was optimized for low cost high volume applications where high converter linearity is required. The high LO suppression of 42 dB yields excellent carrier suppression for modulator applications. 12 MIXERS - SMT General Description Electrical Specifications, TA = +25° C LO = +19 dBm, IF = 100 MHz Parameter Units Min.
