The HMC316MS8 is a miniature double balanced mixer in an 8 lead plastic surface mount package. The passive GaAs schottky diode mixer implements planar on chip Balun transformers, 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 1.5 and 3.5 GHz. At mid-band the mixer provides 7.5 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.
