BB503CCS-TL-E

Overview

The BB503CCS-TL-E is a MOS FET IC designed for UHF/VHF RF amplifier applications, manufactured by Renesas Electronics Corporation. It integrates a built-in biasing circuit to reduce component count and printed circuit board space requirements. The device features low noise performance with a typical noise figure of 1.8 dB at 900 MHz and provides high gain, typically 22 dB at the same frequency. It includes an internal ESD absorbing diode capable of withstanding up to 200V under specific conditions (C=200pF, Rs=0). The component is housed in a mini mold CMPAK-4 package, which is a modification of the SOT-343 form factor.

Feature Summary

• Integrated biasing circuit reduces external parts and PCB area
• Low noise figure of 1.8 dB typ. at 900 MHz
• High power gain of 22 dB typ. at 900 MHz
• Built-in ESD protection withstands 200V

Applications

• UHF/VHF RF amplification systems
• Consumer electronics requiring compact RF stages
• Communication devices utilizing MOS FET amplifiers

Procurement Notes

Verify the exact manufacturer source, as historical data links this part to Hitachi Semiconductor and Renesas Technology Corp. Confirm the CMPAK-4 package designation matches current inventory specifications. Check for RoHS compliance status as original documentation may predate modern environmental directives. Ensure the ESD rating conditions align with system design requirements.

Selection Notes

Select this component for applications requiring a compact UHF/VHF amplifier solution with integrated biasing. The low noise figure makes it suitable for sensitive receiver front-ends. Consider the ESD robustness for environments with static discharge risks. Compare against similar models like BB503M or BB503C if package variations are needed.

Part Context

This part belongs to the family of MOS FET ICs originally developed by Hitachi Semiconductor and later associated with Renesas Technology Corp. It serves as a specialized RF amplifier component. Similar parts in the lineup include BB304M, BB305C, BB402M, and BB405M, which share the built-in biasing feature but may differ in specific electrical characteristics or packaging.

Replacement Considerations

Potential substitutes include BB503M and BB503C from Renesas/Hitachi. Verify pin compatibility and electrical parameters such as gain and noise figure before substitution. The BB503CCS-TL-E specifically denotes the CMPAK-4 package variant.
