High-Power Amplifier MMICs Deliver Low Cost Per Watt

Through use of advanced, 0.25-micron gate length pHEMT GaAs production process technology, two new millimeter-wave high-power MMIC devices have been developed that are said to provide the smallest available physical size and lowest cost per watt output power in the 18- to 32-GHz frequency range. Designated the TGA1135B and TGA1172, the devices provide equipment designers with an efficient, 1W source of millimeter wave power for use in wireless communications products, such as point-to-point or point-to-multipoint radios, satellite communication earth stations, and spacecraft payloads.
The MMICs cover the 18, 23 and 26 GHz microwave radio bands, 24, 28 and 31 GHz Local Multipoint Distribution System (LMDS) bands, and the 18 and 30 KHz satellite communications bands. The TGA1135B costs $49 each/1,000 and TGA1172, $50.
