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 50I while a single
external inductor is used to match the input port to 50I.
The MAX2664 and MAX2665 are available in a 4-bump
(0.8mm x 0.8mm x 0.64mm), lead-free, wafer-level
package (WLP).
