Specifications of MAX2538EVKIT

• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

The MAX2530/MAX2531/MAX2538 EV kits are fully
assembled and factory tested. Follow the instructions in
the Connections and Setup section for proper device
evaluation. Figure 1 shows the schematic. Figures 2
through 7 are component placement guides and PC
board layouts.
This section lists the test equipment recommended to
verify operation of the MAX2530/MAX2531/MAX2538
EV kits. It is intended as a guide only, and some substi-
tutions are possible.
• Two RF signal generators capable of delivering
• An RF spectrum analyzer capable of covering the

Quick Start
USE
• A power supply capable of 50mA at 2.7V to 3.3V
• (Optional) An ammeter for measuring the supply
• 50Ω SMA cables
• (Optional) A network analyzer (HP 8753D, for exam-

of displaying gain vs. a swept frequency band, in
addition to displaying input and output return loss.
