PBV1632S-5DBN8-T

Overview

The Susumu PBV1632S-5DBN8-T is a surface-mount thin-film thermo-variable chip attenuator designed for RF applications. It provides a nominal attenuation of 5 dB with a maximum operating frequency of 3 GHz and a characteristic impedance of 50 Ohms. The device features a maximum Voltage Standing Wave Ratio (VSWR) of 1.3 and supports a power dissipation of 100 mW. It operates within a temperature range of -55°C to +125°C and utilizes silicon technology in a compact SMD package.

Feature Summary

• Thermo-variable design enables dynamic adjustment of attenuation levels via thermal control mechanisms.
• Thin-film construction ensures stable performance across wide frequency ranges up to 3 GHz.
• Compact surface-mount form factor facilitates integration into space-constrained wireless systems.

Applications

• Mobile phone base station signal conditioning
• Wireless remote controller circuitry
• RF test and measurement equipment

Procurement Notes

Verify the specific suffix 'T' against the manufacturer's official documentation to confirm tape-and-reel packaging requirements. Ensure that the selected variant matches the required power rating and thermal characteristics for your specific application environment. Cross-reference the full part number with authorized distributors to confirm current availability and compliance status.

Selection Notes

Select this component when variable attenuation is required rather than fixed values. Consider the thermal management capabilities inherent to the thermo-variable design. Evaluate the 100 mW power limit against system signal levels. Confirm compatibility with 50 Ohm system impedance and verify that the 3 GHz frequency range meets the operational bandwidth needs.
