High-performance Ka-Band power amplifier

Supplier of semiconductor solutions, MACOM Technology Solutions, announced an addition to its portfolio of high-linearity Ka-Band power amplifiers with the introduction of the MAAP-011250. Suited for next generation commercial VSAT outdoor units, the MAAP-011250 utilises a balanced design, giving system designers’ a consistent match regardless of their board impedance.

As the demand for high speed, broadband, data connectivity continues, MACOM is seeing changes in fixed wired networks, such as HFC and Fiber along with terrestrial wireless networks, and SATCOM, in order to meet this demand. As the requirements for increased data rates and bandwidth continue to drive higher power, higher frequency and higher linearity MMICs, MACOM is well positioned to provide both catalogue and custom SATCOM solutions.

With the addition of the four watt amplifier, MACOM now offers 2, 2.3, 3, 4 and 7W power output options spanning frequencies ranging from 27 to 31.5GHz. These new 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 is a balanced four watt, four-stage power amplifier assembled in a lead-free five mm 32-lead AQFN plastic package. This power amplifier operates from 27.5 to 30GHz and provides 24 dB of linear gain, four watt saturated output power and output IP3 of 41dBm while biased at six volts. 

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 PAs to deliver a complete chipset for high-performance wireless broadband data links.
