The TBUC Series from EM Research are Digitally Programmable Block-Up Converters (BUCs). They can convert input frequencies (IF) from 950 – 1950 MHz to output frequencies (RF) from 27.5 – 28.5 GHz (Band 1), 28.5-29.5 GHz (Band 2), and 29-30 GHz (Band 3). These BUCs deliver three block up-converters in a single compact package and any one of three bands can be selected using standard communication protocols such as CAN, RS-232, or I2C. They have integrated filters to suppress undesirable harmonics and maintain low spurious levels. These BUCs have spurious levels of less than -60 dBc and phase noise of -78 dBc/Hz (at 1 kHz offset). They require a DC supply of 12 V, consume 950 mA of current, and offer low power consumption. These converters are available in an enclosure and are ideal for SATCOM applications.
