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. It is especially suited for cellular base station, cable modem, and fixed wireless access systems that operate between 700 and 1100 MHz. The mixer provides 9.5 dB conversion loss and +26 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 40 dB yields excellent carrier suppression for modulator applications.
