Amplifier range expands

Louise Smyth

Macom Technology Solutions has expanded its portfolio of high-linearity Ka-Band power amplifiers with the introduction of the MAAP-011250. Aimed at next generation commercial VSAT outdoor units, the MAAP-011250 utilises a balanced design giving system designers’ a consistent match regardless of their board impedance.

With the addition of the 4W amplifier, Macom now offers 2, 2.3, 3, 4 and 7W power output options spanning frequencies ranging from 27 to 31.5 GHz. 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 4 W, 4 stage power amplifier assembled in a lead-free 5 mm 32-lead AQFN plastic package. This power amplifier operates from 27.5 to 30 GHz and provides 24 dB of linear gain, 4 W saturated output power and output IP3 of 41 dBm while biased at 6 V. 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.
