HMC350MS8 v01.0301 MICROWAVE CORPORATION GaAs MMIC HIGH IP3 SINGLEBALANCED MIXER, 0.6 - 1.2 GHz Typical Applications Features The HMC350MS8 is ideal for: Conversion Loss: 8.0 dB • Cellular Basestations Input IP3: +27 dBm • Cable Modems Input IP2: +45 dBm • Fixed Wireless Access Systems Input P1dB: +17 dBm Functional Diagram General Description The HMC350MS8 is a miniature single 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 7.5 dB conversion loss and +25 dBm IIP3 with LO drive levels of +19 dBm at mid-band. The design was optimized for low cost high volume applications where high converter linearity is required.
