| HMC351S8 / 351S8E v03.0705 GaAs MMIC HIGH IP3 DOUBLEBALANCED MIXER, 0.7 - 1.2 GHz Typical Applications The HMC351S8 / HMC351S8E is ideal for: * Cellular Basestations Features Conversion Loss: 9.0 dB LO/IF Isolation: 35 dB LO/RF Isolation: 42 dB Input IP3: +25 dBm Input IP2: +48 dBm 7 MIXERS - SMT * Cable Modems * Fixed Wireless Access Systems Functional Diagram General Description The HMC351S8 & HMC351S8E are double balanced mixers in 8 lead plastic surface mount packages. 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. Electrical Specifications, TA = +25 C LO = +19 dBm, IF = 100 MHz Parameter Min.
