VHF/UHF Low-Noise Amplifiers
General Description
Features
UHF and VHF Frequency Range
MAX2664: 470MHz to 860MHz
MAX2665: 75MHz to 230MHz
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.
High Gain: 15dB

CAUTION! ESD SENSITIVE DEVICE
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

RF Output and Bypass Control (see the Applications Information section). RFOUT is

RFOUT/CTRL
Input and Output Matching
Detailed Description
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. Table 1 lists typical device S-parameter
values. The devices integrate an on-chip 50I output-
matching network, eliminating the need for external
matching components.
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.

Active Bypass Mode Control
Table 5. Logic Table
The devices’ RFOUT/CTRL pin is used to control the
bypass mode of the LNA. When set to logic-high through
an external 1kI resistor, the devices’ active mode is
enabled. Conversely, when connected to logic-low,
the devices’ bypass mode is disabled. An external
DC-blocking capacitor should be used to isolate the
control function of this dual-purpose pin (see the Typical
Application Circuit).

tional decoupling capacitors. Locate these additional
capacitors further away from the device package. Proper
grounding of the GND pin is essential. If the PCB uses
a topside RF ground, connect it directly to the GND pin.
For a board where the ground is not on the component
layer, connect the GND pin to the board with multiple
vias close to the package.
