MAX2665

VHF/UHF Low-Noise Amplifiers

Ultra-Small VHF and UHF LNAs Improve Receive Sensitivity for TV and FM-Enabled Phones


Please check latest availability status for a specific part variant.

Description

The MAX2664 and MAX2665 are ultra-compact LNAs for VHF/UHF applications. These devices incorporate a broadband LNA with an integrated bypass switch. The MAX2664 covers the UHF frequency range from 470MHz to 860MHz, and the MAX2665 covers the VHF frequency range from 75MHz to 230MHz.

Each device has a zero-power bypass mode for improved high-signal-level handling conditions. Additionally, the output port is internally matched to 50Ω while a single external inductor is used to match the input port to 50Ω.

The MAX2664 and MAX2665 are available in a 4-bump (0.8mm x 0.8mm x 0.64mm), lead-free, wafer-level package (WLP).
