| RoHS Compliant 1.25 W VSAT Power Amplifier 13.75--14.5 GHz Features * * * * * * * * Saturated Output Power: 31 dBm Typical High Linear Gain: 34 dB Typical High Power Added Efficiency: 31 % at PSAT 50 Input / Output Match Lead-Free 6 mm 28-lead PQFN Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound RoHS* Compliant and 260C Reflow Compatible MAAPSS0111 V2P Functional Schematic Description The MAAPSS0111 is a four stage MMIC power amplifier designed specifically for Ku-Band VSAT applications. It can be used as either a driver or an output stage amplifier. The MAAPSS0111 is fully matched input and output to 50 ohms which eliminates any sensitive external RF tuning components. The device is packaged in a lead free 6 mm 28-lead PQFN leadless package for high volume manufacturing. The MAAPSS0111 is fabricated using a high reliability self-aligned gate MESFET process, MSAG, to realize good power added efficiency and gain. The MSAG process features full passivation for high performance and reliability.

A substrate thickness of 20 mils (0.508 mm) maximum is recommended to minimize thermal resistance and ground impedances. RF transmission line impedance must be 50 ohms (w = 42 mils (1.0668 mm) for t = 20 mils (0.508 mm), Rogers 4003). The board must provide low thermal resistance from package base to heat sink to accommodate the 3 W typical power dissipation. Metal foil thickness in the vias is critical to thermal resistance. The recommended metalization is 1 oz (35 mm minimum thickness). The application board is configured with 36 vias, each 12 mil (0.3048 mm) in diameter beneath the package base. Conductive via fill material is recommended to minimize thermal resistance and to prevent solder from wicking into vias. The exposed package pad must be properly soldered to the board. Case temperature is measured at the interface between the package bottom and circuit board. * North America Tel: 800.366.2266 / Fax: 978.366.2266 * Europe Tel: 44.1908.574.200 / Fax: 44.1908.574.300 * Asia/Pacific Tel: 81.44.844.8296 / Fax: 81.44.844.8298 Visit www.macom.com for additional data sheets and product information.
