CHM1481-QFG/20 United Monolithic Semiconductors
MFG Part Number: CHM1481-QFG
UMS 6-9 GHz direct quadrature modulator packaged integrates a double-balanced mixer (LO suppression and Image Rejection) and a LO buffer.  It can be used for both LSB and USB configurations.  The high carrier suppression, the side band rejection and the very low out-of-band noise density combined with the baseband inputs which supports modulation from DC to 250 MHz makes this circuit a very versatile modulator for high performance systems.  Moreover it is proposed in standard surface mount package (QFN). The overall power supply is as low as 4V/110mA. The circuit is mainly dedicated to Point to Point and Point to Multi-Point systems and also well suited for a wide range of microwave and millimetre wave applications and systems.  It is developed on a 0.5µm E/D mode pHEMT process, and will be available in a standard surface mount (32 lead) QFN5x5, compliant with the Restriction of Hazardous Substances (RoHS) European Union directive 2002/95/EC.
