HMC6787ALC5ATR (ANALOG DEVICES)

The HMC6787ALC5A is a compact GaAs MMIC I/Q variable gain upconverter in a leadless RoHS compliant SMT package. This device provides a small signal conversion gain of 11 dB with 17 dBc of sideband rejection, and 13 dB of gain control. The HMC6787ALC5A utilizes a RF variable gain amplifier preceded by an I/Q mixer where the LO is driven by a X2 multiplier. IF1 and IF2 mixer inputs are provided and an external 90° hybrid is needed to select the required sideband. The I/Q mixer topology reduces the need for filtering of the unwanted sideband. The HMC6787ALC5A is a much smaller alternative to hybrid style single sideband upconverter assemblies and it eliminates the need for wire bonding by allowing the use of surface mount man- ufacturing techniques.
