MSA-0505-STRG – AVAGO

The MSA-0505-STRG, manufactured by AVAGO, is a silicon bipolar monolithic microwave integrated circuit (MMIC) amplifier designed for applications within the 20 MHz to 2.3 GHz frequency range. It is fabricated using a high-frequency process optimized for low noise figure and moderate power output. The device is housed in a miniature 5-pin plastic surface-mount package (likely SOT-89 or similar), facilitating automated assembly and minimizing parasitic inductance. Typical applications include use as a low-noise amplifier (LNA) in ISM band receivers, IF amplifiers, and general-purpose gain stages within communication systems. Performance characteristics include a typical gain of 14 dB at 1 GHz, a noise figure of approximately 3.5 dB, and an output power at 1 dB compression (P1dB) of around 5 dBm. The MSA-0505-STRG requires a single positive DC supply voltage, typically +5V, and is internally biased for simplified implementation.
