描述 Description

The SE5003L is a 5GHz power amplifier offering highlinear power for wireless LAN applications. TheSE5003L incorporates a power detector for closedloop monitoring and control of the output power.

The SE5003L offers high integration for a simplifieddesign, providing quicker time to market and higherapplication board production yield. The deviceintegrates the input match, the inter-stage match, theoutput match, the power detector with 15dB ofdynamic range and a 3.8GHz notch filter. Only 6external decoupling capacitors are required tocomplete the design.

For wireless LAN applications, the device meets therequirements of IEEE802.11a & 802.11n, and deliversapproximately 23dBm of linear output power at 5V.

The SE5003L integrates the reference voltagegenerator. A 2.85V reference voltage on VREF is allthat is required to enable or disable the poweramplifier.

簡介

SE5003L屬于RF/IF射頻/中頻RFID的射頻放大器。由制造生產的SE5003L射頻放大器在射頻應用中，射頻放大器產品可用于信號增益和緩沖。這些產品與通用運算放大器的不同之處在于，它們通常適用于更高的頻率，更傾向于提供不可調節(jié)的固定增益，并且輸入或輸出阻抗值符合常用傳輸線特性阻抗。
