MMA25312BT1 – FREESCALE

The MMA25312BT1, manufactured by Freescale Semiconductor, is a monolithic microwave integrated circuit (MMIC) amplifier designed for WiMAX applications operating within the 2.3 GHz to 2.7 GHz frequency range. This device is fabricated utilizing a GaAs pHEMT process, enabling high gain and low noise figure performance critical for front-end receiver amplification. The amplifier provides a typical gain of 25 dB with a corresponding noise figure of 2.5 dB at 2.5 GHz. It features integrated input and output matching networks optimized for a 50-ohm impedance environment, simplifying system integration and minimizing external component count. The MMA25312BT1 is housed in a 12-pin Quad Flat No-Lead (QFN) package with a 3×3 mm footprint, offering excellent thermal performance and compact size for space-constrained applications. The device operates from a single positive supply voltage, typically +5V, and exhibits good linearity performance, characterized by an output IP3 of +35 dBm.
