MMA053AA

RF Amplifiers Overview

The MMA053AA is a DC–8 GHz Gallium Arsenide (GaAs) Monolithic Microwave Integrated Circuit (MMIC) pseudomorphic High Electron Mobility Transistor (pHEMT) distributed power amplifier. It delivers 1.0W output power with 17 dB gain and a 3 dB noise figure. Operating at 11 V supply voltage, it draws 410 mA current. Key metrics include a P1dB of 29 dBm, OIP3 of 43 dBm, and input return loss of -17 dB. The device operates within a temperature range of -55°C to +85°C. Packaged as a bare die in waffle packs, it features internally matched 50 Ohm I/Os for direct integration.

RF Amplifiers Procurement Notes

Verify the specific manufacturer source, as the component appears listed under both Microchip Technology and MACOM in distributor catalogs. Confirm the exact frequency range specification (DC-6 GHz vs DC-8 GHz) against the official datasheet provided by the supplier. Ensure the package type is correctly identified as a bare die in waffle pack format rather than a standard surface-mount package.

RF Amplifiers Selection Notes

Select this component for applications requiring high output power up to 1.0W across a wide DC-to-8 GHz bandwidth. The internal 50 Ohm matching reduces external passive component requirements. Consider the bare die form factor when designing PCB layouts or MCMs, as it requires specialized mounting techniques compared to packaged ICs.

RF Amplifiers Part Context

This MMIC belongs to the family of GaAs power amplifiers designed for broadband RF applications. It serves as a high-power stage in signal chains where linearity and gain are critical. The distributed architecture supports operation from DC through microwave frequencies, distinguishing it from narrowband tuned amplifiers.
