MAX2644 Evaluation Kit
General Description
The MAX2644 evaluation kit (EV kit) simplifies the evalu-
ation of the MAX2644 low-noise amplifier (LNA). The kit
enables testing of the device’s performance and
requires no additional support circuitry. The signal input
and output use SMA connectors to facilitate easy con-
nection of RF test equipment.
The MAX2644 EV kit is fully assembled with the
MAX2644 and incorporates matching components opti-
mized for a 2450MHz RF frequency operation.
Features
o Easy Evaluation of MAX2644
o +2.7V to +5.5V Single-Supply Operation
o Matched to 50Ω at 2450MHz
o Fully Assembled and Tested

Quick Start
The MAX2644 EV kit is fully assembled and factory test-
ed. Follow the instructions in the Connections and
Setup section for proper device evaluation.
Test Equipment Required
• One RF signal generator capable of delivering
10dBm of output power and a frequency range
covering the MAX2644 (2400MHz to 2500MHz, for
example)
• An RF spectrum analyzer that covers the operating
frequency range (HP8561E, for example)
• DC power supply capable of supplying +2.7V to
+5.5V and 20mA of current
• Two 50Ω coaxial cables with SMA connectors
• (Optional) An ammeter to measure supply current
• (Optional) A noise figure meter
• (Optional) Network analyzer to measure gain and
return loss
Connections and Setup
Checking Power Gain
1) Connect a DC supply (preset to +3.0V) to the VCC
and GND terminals (through an ammeter, if desired)
on the EV kit.
2) Set the RF generator for a 2450MHz output frequen-
cy at a -30dBm power level. Disable RF generates
