General Description

The MAX2649 evaluation kit (EV kit) simplifies evalua-

tion of the MAX2649. The EV kit allows the evaluation of

the LNA without requiring additional support circuitry.

The signal input and output use SMA connectors to

simplify the connection of RF test equipment.

The MAX2649 EV kit is assembled with an associated

IC and incorporates input and output matching compo-

nents optimized for RF frequencies from 5150MHz to

5350MHz. For operation outside this range, refer to the

MAX2649 data sheet.

Features

o +2.7V to +3.6V Single-Supply Operation

o 50Ω SMA Inputs and Outputs on RF Ports for

Easy Testing

o All Matching Components Included

o Fully Assembled and Tested

Quick Start

The MAX2649 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

Table 1 lists the required test equipment to verify the

MAX2649 operation. It is intended as a guide only, and

some substitutions are possible.

Connections and Setup

This section provides a step-by-step guide to operate

and test the device’s functions. Do not turn on DC

power or RF signal generators until all connections are

made.

Testing the Supply Current

1) Connect a DC supply set to +3.0V (through an

ammeter if desired) to the VCC (J3) and GND (J4)

terminals on the EV kit. If available, set the current

limit to 30mA. Do not turn on the supply.
