4W Ka-Band power amplifier extends Macom’s satcom offering

The MAAP-011250 is a balanced 4.0W power amplifier that has been released by Macom Technologies. It operates from 27.5 to 30GHz making it well suited for satellite communications (satcom) and VSAT applications.

The balanced design can enable consistent matching to 50 Ohms at the input and output, confirms Macom Technologies.

The MAAP-011250 complements its portfolio of Ka-Band gain block amplifiers, drivers, mixers and Pas. Macom Technologies says that it delivers a complete chipset for high-performance wireless broadband data links.

The MAAP-011250 is suitable for next-generation commercial VSAT outdoor units, with a balanced design, giving system designers’ a consistent match regardless of their board impedance, explains Macom.

The demand for high speed, broadband, data connectivity is driving changes in fixed wired networks, such as HFC and fibre as well as terrestrial wireless networks, and satcom. As the requirements for increased data rates and bandwidth continue to drive higher power, higher frequency and higher linearity MMICs, Macom provides both catalogue and custom satcom options.

With this latest addition, Macom offers 2.0, 2.3, 3.0, 4.0 and 7.0W power output options spanning frequencies ranging from 27 to 31.5GHz. These GaAs-based Ka-Band PAs can provide strong linear gain, which is expected to enable customers to efficiently increase the power from the input to the output port with minimal tradeoffs.

The MAAP-011250 four-stage power amplifier is assembled in a lead-free 5.0mm 32-lead AQFN plastic package. Operating from 27.5 to 30GHz, it provides 24dB of linear gain, 4.0W saturated output power and output IP3 of 41dBm while biased at 6.0V.

The MAAP-011250 can be used as a power amplifier stage or as a driver stage in higher power applications. The amplifier complements Macom’s portfolio of Ka-Band gain block amplifiers, drivers,mixers and power amplifiers for wireless broadband data links.
