HMC351S8 / 351S8E v04.0408 GaAs MMIC HIGH IP3 DOUBLE- BALANCED MIXER, 0.7 - 1.2 GHz Typical Applications Features The HMC351S8 / HMC351S8E 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 9 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 com- ponents. 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 Specifi cations, T = +25 C A LO = +19 dBm, IF = 100 MHz Parameter Units Min. Typ. Max.
