General Description

The MAX2430 is a versatile, silicon RF power amplifier that operates directly from a 3V to 5.5V supply, making it suitable for 3-cell NiCd or 1-cell lithium-ion battery applications. It is designed for use in the 800MHz to 1000MHz frequency range and, at 915MHz, can produce +21dBm (125mW) of output power with greater than 32dB of gain at VCC = 3.6V.

Features

♦ Operates Over the 800MHz to 1000MHz Frequency Range

♦ Delivers 125mW at 915MHz from +3.6V Supply (100mW typical from +3.0V supply)

♦ Operates Directly from 3-Cell NiCd or 1-Cell Lithium-Ion Battery

♦ Over 32dB Power Gain

♦ RF Power Envelope Ramping is Programmable with One External Capacitor

♦ Input Matched to 50Ω (VSWR < 2:1)

♦ 15dB Output Power Control Range

♦ 1µA Typical Shutdown Current
