The MAX2664/MAX2665 are low-power LNAs designed
for VHF/UHF applications. The devices feature an inter-
nal LNA bypass control mode for better linearity under
high-input-signal power conditions. The devices are
offered in a small WLP package.

Detailed Description
CC
Ground. Connect to the PCB ground plane with minimal trace inductance.
Supply Voltage. Bypass to ground with a 1000pF capacitor as close as possible to the IC.
RF Input. Requires an external matching inductor and DC-blocking capacitor. The nominal
internal DC voltage is 750mV.
RF Output and Bypass Control (see the Applications Information section). RFOUT is
internally matched to 50I and incorporates an internal DC-blocking capacitor.

Only an inductor in series with a DC-blocking capaci-
tor is needed to form the input-matching network. The
Typical Application Circuit shows the recommended
input-matching network. These values are optimized
for the best simultaneous gain, noise figure, and return
loss performance. Tables 1 and 2 list typical device
S-parameter values. The devices integrate an on-chip
50I output-matching network, eliminating the need for
external matching components.
