MACOM Technology Solutions Inc of Lowell, MA, USA (which makes semiconductors, components and subassemblies for analog RF, microwave, millimeter-wave and photonic applications) has launched the MAAP-011247 and MAAP-011248 distributed power amplifiers. Operating from DC to 22GHz, they can be used as a power amplifier stage or as a driver stage in higher-power applications, and are suitable for test & measurement (T&M), electronic counter measures (ECM) and radar applications.
The MAAP-011247, a 2W amplifier, features 12dB of linear gain, 33dBm of saturated output power and what is claimed to be the industry's highest output power for a monolithic microwave integrated circuit (MMIC) amplifier covering DC-22GHz. The device is fully matched across the band and provides 42dBm of OIP3 (output third-order intercept point) linearity.
The MAAP-011248, a 1W amplifier, offers 12.5dB of linear gain, 30dBm of saturated output power and can be operated over a drain voltage of 9-12V for optimization of RF power versus DC power dissipation. The device provides 41dBm of OIP3 linearity.
Both devices offer an integrated temperature-compensated output power detector, and are available as bare die (measuring 2.99mm x 1.5mm x 0.1mm) or in 5mm 32-lead QFN packages.
"The MAAP-011247 and MAAP-011248 are the first of four new distributed amplifiers designed to deliver high gain and power in compact bare die or QFN packaged solutions," says Graham Board, senior director, Multi-Market Products. "Two additional distributed amplifiers with 1/4W and 1/2W output power are scheduled for release over the next two quarters. This complete family of distributed amplifiers will offer customers a full range of power levels to solve their most challenging wideband test & measurement and mission-critical aerospace & defense system requirements."
