Technology Overview: 25W X-Band GaN PA MMIC Design
2014-10-24 13:29:23| rfglobalnet Home Page
Gallium Nitride (GaN) MMIC processes suitable for operation at microwave frequencies are now commercially available from a number of vendors worldwide. The high breakdown voltage of GaN transistors and their ability to operate reliably at high junction temperatures make them well suited for the realization of high-power amplifiers. This case study describes the design and performance of a 25W X-band GaN PA MMIC developed with a 0.25µm GaN on SiC process.

X-Band 15 W High Power Amplifier suits radar applications.
2014-07-30 14:31:59| Industrial Newsroom - All News for Today
Suited for X-band pulsed applications, MAAP-015036 features saturated pulsed output power of 42 dBm, signal gain of 17 dB, and typical 43% power added efficiency. This 2-stage, 8.5–10.5 GHz, GaAs MMIC power amplifier can be biased using direct gate voltage or on-chip gate bias circuit. Dual-sided bias architecture promotes flexible assembly and board design. Specific applications include marine, weather, and surface-movement radar as well as perimeter security and communication links.
