Overview

  • UHF and VHF Frequency Range
    • MAX2664: 470MHz to 860MHz
    • MAX2665: 75MHz to 230MHz
  • Low Noise Figure
    • MAX2664: 1.2dB
    • MAX2665: 1.1dB
  • High Gain: 15dB
  • Zero-Power Bypass Mode
  • Single +2.4V to +3.5V Supply Voltage
  • Low Current: 3.3mA
  • Small Footprint: 0.8mm x 0.8mm
  • Thin Profile: 0.64mm

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).
