MSA-0611-TR1

RF Amplifiers Overview

The MSA-0611-TR1 is a silicon bipolar Monolithic Microwave Integrated Circuit (MMIC) RF amplifier housed in an SOT-143 surface-mount package. It operates within a frequency range of 0 Hz to 700 MHz, providing a typical gain of 18 dB at a test frequency of 500 MHz. The device functions on a single 4 V supply with a current consumption of 20 mA. Key performance metrics include a noise figure of 3 dB and a third-order intercept point (OIP3) of 14 dBm. Power dissipation is rated at 125 mW, with a maximum operating temperature of +150°C.

RF Amplifiers Procurement Notes

This component is officially classified as obsolete and no longer manufactured by Broadcom Limited. Availability is restricted to existing stock or surplus channels. Verification of authenticity and lot traceability is critical when sourcing from non-direct suppliers. Ensure that any available units meet original specification standards before integration into new designs.

RF Amplifiers Selection Notes

Engineers should consider this part only for legacy system maintenance or repair scenarios due to its discontinued status. For new designs, alternative modern RF amplifiers with similar gain and frequency characteristics are recommended to ensure long-term supply chain stability. Evaluate pin compatibility and thermal requirements if substituting within existing footprints.

RF Amplifiers Part Context

The MSA-0611 series represents a line of low-cost MMICs designed for broad RF applications. Variants such as the MSA-0611-TR1G differ primarily in packaging suffixes indicating tape-and-reel configuration. The product falls under the Wireless & RF Integrated Circuits subcategory, serving as a foundational active component for mid-frequency signal processing tasks.

RF Amplifiers Replacement Considerations

Public confirmed substitute part numbers are not explicitly documented in the provided source material. Engineers must perform independent cross-reference analysis using key parameters: 18 dB gain, 0-700 MHz range, SOT-143 package, and 4V single-supply operation.
