TSS-53LNB3+

RF Amplifiers Overview

The TSS-53LNB3+ is a low-noise bypass amplifier from Mini-Circuits, operating within a frequency range of 500 MHz to 5 GHz. It provides a typical gain of 18.7 dB with a noise figure of 1.7 dB. The device operates on a single 5 V supply, drawing 82 mA of current. Key performance metrics include a P1dB compression point of 19.2 dBm and an OIP3 of 30.9 dBm. It features an input return loss of 16.9 dB and dissipates up to 700 mW of power. The component is housed in an MCLP-12 (3x3 mm) surface-mount package and functions reliably across temperatures from -40°C to +85°C.

RF Amplifiers Procurement Notes

Verify the specific suffix designation when ordering, as variations such as TSS-53LNB+ or TSS-53LNB-DG+ exist. Confirm that the required package type matches the application design, distinguishing between the standard packaged unit and die options. Ensure compatibility with the intended supply voltage and thermal management requirements before finalizing procurement specifications.

RF Amplifiers Selection Notes

Select this component for designs prioritizing low noise and wideband performance in the UHF to microwave spectrum. Consider the MCLP-12 footprint constraints during layout planning. Evaluate the trade-off between the 18.7 dB gain and the 1.7 dB noise figure against system sensitivity requirements. Verify that the 5 V supply capability aligns with the overall power budget of the target electronic assembly.
