The HMC216MS8 is an ultra miniature doublebalanced FET mixer in an 8 lead plastic surface mount package (MSOP). This MMIC mixer is constructed of switched GaAs FETs and novel planar transformer baluns on the chip. In addition to an LO drive of +3 to +13 dBm, a gate voltage of Vgg= -0.9 to 1.6 Vdc is required. The device can be used as an up, or downconverter for 1900 or 2400 MHz applications. It is especially suited for miniature basestations, WLAN, PCMCIA, and portable wireless applications. The consistent MMIC performance will improve system operation and assure regulatory compliance. The MSOP8 package is the smallest footprint available for a complete double-balanced mixer, 0.118" x 0.190" (3.0mm x 4.9mm). At a height of 0.040" (1.0mm) this is the thinnest SMT FET mixer available today.
