Macom adds 2 and 4W Ka-Band Power Amplifiers
RF, microwave and optical semiconductor specialist Macom has announced the MAAP-011246, a new 2W power amplifier, and the MAAP-011139, a new 4W power amplifier in a surface mount package.
These four stage, fully matched GaAs pHEMT power amplifiers are well suited to Ka-Band satellite communications applications, and provide high linearity for either final power amplification stages or driver stages in higher power applications.
The MAAP-011246 operates from 27.5 to 31.5GHz, providing customers with 23dB of linear gain, 2W saturated output power and 24 percent added efficiency.
The device is offered in a 5x5 mm 32-lead QFN package and offers an IM3 level of -25 dBc at 27 dBm Pout/tone, making the power amplifier suitable for high-performance commercial uplink terminal applications.
The MAAP-011139 is offered in a 5x5 mm 32-lead QFN package and operates from 28.5 to 31.0 GHz while providing 22dB linear gain and 23 percent added efficiency. The device delivers 4W saturated output power and greater than 27dBm Pout/tone while maintaining IM3 levels of 30dBc, which is twice the linear performance of competing alternatives.
"The superior linearity performance of the MAAP-011246 and MAAP-011139 are further complemented by their high gain, power added efficiency and availability in SMT QFN packages," said Paul Beasly, product manager, Macom. "The addition of these 2W and 4W packaged power amplifiers to Macom's complete chip-set solution offers customers increased performance and flexibility in next generation Ka-Band VSAT systems."
