CHELMSFORD, Mass., 29 Aug. 2010. Hittite Microwave Corp. in Chelmsford, Mass., is introducing two ultra-low-noise programmable frequency dividerRF and microwave components for signal generation in military communications applications that operate from 100 MHz to 15 GHz, as well as in test and measurement equipment and laboratory systems. The HMC862LP3E and HMC905LP3E are SiGe BiCMOS low noise programmable frequency dividers in SMT packages.

The HMC862LP3E can be programmed to divide from N = 1, 2, 4, 8 in the 100 MHz to 15 GHz input frequency range. The HMC905LP3E can be programmed to divide from N = 1, 2, 3, 4 in the 400 MHz to 6 GHz frequency range.

The HMC862LP3E has low phase noise of -153 dBc/Hz at offset frequencies greater than 100 kHz, wide frequency range, and flexible division ratio for wideband communications systems. The HMC905LP3E has high level output power of as much as 6 dBm single ended, with a low SSB phase noise of -158 dBc/Hz at offset frequencies greater than 100 kHz, and 50 percent duty cycle for low-noise clock generation, LO generation, and LO drive applications. The HMC905LP3E also incorporates configurable bias and output power controls, as well as a power down have. Both HMC862LP3E and HMC905LP3E provide good input to output isolation and fast start up time.

The HMC862LP3E and HMC905LP3E are housed in a miniature 3-by-3-millimeter RoHS compliant QFN leadless SMT package and are specified for operation over -40 to 85 degrees Celsius. For more information contact Hittite online at www.hittite.com.
