RF Amplifiers Procurement Notes

Verify the specific suffix BLK against official Broadcom documentation to confirm package type and tape-and-reel specifications. Confirm that the obsolete status noted by distributors does not preclude availability through authorized channels or approved alternatives. Cross-reference the MCOB-6 package dimensions with your PCB layout requirements before finalizing procurement decisions.

RF Amplifiers Selection Notes

Select this component when designing for GNSS or cellular bands requiring minimal noise contribution. Its ability to maintain performance at 1V makes it ideal for battery-constrained portable devices. Ensure the design accommodates the MCOB-6 footprint and thermal dissipation limits specified for the 54mW power dissipation rating.

RF Amplifiers Part Context
