Cree has launched a high power Ku-Band MMIC that operates from 13.5 to 14.75 GHz in the commercial satcom bands. This GaN MMIC two-stage high power amplifier (HPA) has been developed for the SATCOM industry and can achieve powers of up to 30 W. The CMPA1D1E025F is more efficient than the Ku-Band TWT or GaAs solutions that are used in the industry.
The CMPA1D1E025F is available in a 10-lead, metal/ceramic flanged package that measures 25 × 9.6 mm and requires a supply of 40 V Vdd. It delivers satcom measured performance of 20dB linear gain at 42dBm average output power, while maintaining linearity under the -33dBc OQPSK signal, and with adjacent channel power at a drain efficiency of 20%.
In addtion to its wider bandwidth, the device also has a higher breakdown voltage, power density, and thermal conductivity than comparable Si, GaAs, or GaN-on-Si transistors. The CMPA1D1E025F will be stocked by both Digi-Key and Mouser by mid-summer 2015.
