VMMK-3803-TR2G

RF Amplifiers Overview

The VMMK-3803-TR2G is a radio frequency amplifier integrated circuit manufactured by Broadcom Limited. It is designed for WiMAX applications, operating within a frequency range of 3GHz to 11GHz. The device provides a gain of 20dB and features an input return loss of 15dB. It requires a supply voltage of 3V and draws a supply current of 20mA. The component is housed in a 0402 surface-mount package and is available in tape and reel packaging.

RF Amplifiers Feature Summary

• Provides high gain performance suitable for wideband amplification
• Operates across a broad frequency spectrum from 3GHz to 11GHz
• Designed specifically for WiMAX signal processing applications

RF Amplifiers Applications

• WiMAX system front-end modules
• Ultra-wideband (UWB) low noise amplifier stages
• RF signal amplification in wireless communication devices

RF Amplifiers Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as variants exist with different handling requirements. Confirm that the obsolete status does not impact long-term supply chain stability for existing designs. Check RoHS compliance documentation if environmental regulations are a constraint for the target market. Ensure the 0402 footprint matches the PCB layout constraints precisely.

RF Amplifiers Selection Notes

Select this component when a compact solution is required for WiMAX bands between 3GHz and 11GHz. The 0402 package offers space efficiency for dense layouts. Consider the 20mA supply current for power budget calculations. Evaluate the 20dB gain against system link budget requirements. Compare with other Broadcom VMMK series parts if shutdown functionality or different gain profiles are needed.

RF Amplifiers Part Context

This part belongs to the VMMK series of RF amplifiers from Broadcom Limited. It is distinct from the TR1G variant, which includes shutdown functionality, and the BLKG bulk package variant. The TR2G designation specifically indicates the tape and reel packaging format. It serves as a specialized active component for high-frequency wireless infrastructure and mobile terminals.

RF Amplifiers Replacement Considerations

Direct substitutes include the VMMK-3803-BLKG for bulk packaging needs and the VMMK-3803-TR1G if shutdown control is required. Note that the VMMK-3803-TR1G may have functional differences due to the added shutdown pin. Verify pin compatibility and electrical parameters before swapping between these variants.
