MGA-52543-TR2G

RF Amplifiers Overview

The MGA-52543-TR2G is a GaAs MMIC low noise amplifier from Broadcom Limited, designed for wideband applications. It operates within a frequency range of 400 MHz to 6 GHz. The device provides a typical gain of 13 dB to 15.5 dB with a noise figure between 1.9 dB and 2.3 dB. Key performance metrics include a P1dB compression point of 17.4 dBm and an OIP3 of 31.7 dBm at 1.9 GHz. It requires a supply voltage of 5 V and draws approximately 53 mA of current. The component is housed in a compact SOT-343 package.

RF Amplifiers Procurement Notes

This component is officially classified as obsolete by the manufacturer and is no longer in active production. Availability is restricted to existing stock or third-party distributors. Verification of authenticity and lot traceability is critical due to the end-of-life status. Engineers should confirm lead time constraints and potential counterfeit risks when sourcing from non-authorized channels. Design-in support may be limited.

RF Amplifiers Selection Notes

Select this part only if the specific 400 MHz to 6 GHz bandwidth and GaAs technology align with system requirements. Consider the trade-off between its moderate noise figure and power consumption against modern alternatives. Verify that the SOT-343 footprint fits the PCB layout. Since it is obsolete, ensure long-term supply chain stability is not a project constraint before finalizing the design.

RF Amplifiers Part Context

The MGA-52543 belongs to Broadcom's MGA series of monolithic microwave integrated circuits. These devices are engineered for wireless communications, offering a balance of gain, noise, and linearity. The TR2G suffix indicates a tape-and-reel packaging format compliant with RoHS standards. This series was widely used in early-generation mobile and WLAN hardware before newer, more efficient MMICs became available.

RF Amplifiers Replacement Considerations

Public confirmed substitute part numbers are not explicitly listed in the provided documentation. As the part is obsolete, engineers must evaluate cross-reference data from distributor databases or consult Broadcom for recommended upgrades. Ensure any replacement matches the SOT-343 package and electrical specifications for direct pin-to-pin compatibility.
