[原创] IDT F2480 400－3000MHz模拟可变增益放大器解决方案

IDT公司的F2480是工作在400-3000MHz的模拟可变增益放大器(AVGA),最大级联增益12dB,连续增益范围36dB,极好的线性+41.5dBm OIP3,噪音4.3dB,采用ICC 106mA可输出+41.5dBm输出IP3(900MHz),主要用在多模式多载波接收器,PCS1900基站,DCS1800基站,WiMAX和LTE基站,UMTS/WCDMA 3G基站,PHS/PAS基站,点对点通信,宽带中继,GPS接收器,分布天线系统,线缆基础设备和数字无线电.本文介绍了F2480主要特性,框图和评估板F2480EVBI主要特性,电路图和材料清单.

The F2480 is a 400 to 3000 MHz RF Analog Variable GainAmplifier (AVGA) that can be used in receivers, transmitters andother applications. Either the amplifier or voltage variableattenuator (VVA) can be configured as the first stage in thecascade.

The F2480 RF AVGA provides 12dB typical maximum cascadegain (no attenuation) with 4.3dB noise figure (amplifier as firststage) and 36dB gain adjustment designed to operate with asingle +5V supply. Nominally, the amplifier offers +41.5dBmoutput IP3 using 106mA of ICC.

This device is packaged in a 5 x 5 mm, 32-pin TQFN with 50;single-ended RF input and RF output impedances for ease ofintegration into the signal-path lineup.
