4 W Ka-band Power Amplifier
The MAAP-011233 is a 4-stage, 4 W power amplifier assembled in a lead-free, 5 mm 32-lead AQFN plastic package and is fabricated using a GaAs pHEMT process that has full passivation for enhanced reliability. It operates from 28.5 to 31 GHz and provides 26 dB of linear gain, 27.5% efficiency while biased at 6 VDC, and is well suited for Ku-band VSAT communications systems. IM3 is -27 dBc at 29 dBm/tone, power-added efficiency is 27.5% at P3dB, maximum input power is 14 dBm, input and output return loss is 20 dB, junction temperature is 150° C, and operating temperature range is -40°C to +85°C. The device’s very small size and simple bias allow easy placement on the system board and input and output ports are DC de-coupled internally. It requires a power supply providing 6 VDC at 2 A.
