Product Details:

AD8348是一款宽带Orthogonal demodulator，集成有中频(IF)可变增益放大器(VGA)和Baseband amplifier，适用于通信接收机，可进行从中频直接到基带频率的正交解调。基带放大器可以与双通道ADC直接接口，如AD9201、AD9283和AD9218等，用于数字化和后处理。

中频输入信号通过X-AMP® VGA馈入两个吉尔伯特混频器中。中频VGA提供44 dB的增益控制。精密增益控制电路为VGA设置线性dB增益特性，并提供温度补偿。LO正交分相器采用2分频分频器，在整个工作频率范围内实现高正交精度和幅度平衡。

Manufactured using an advanced bipolar process, the AD8348 operates from a single 3 V or 5 V supply and is available in a space-saving 28-pin ultra-thin shrink miniature (TSSOP) package rated for a temperature range of –40ºC to +85ºC.

Samples and evaluation boards are available in the AD8348ARU and AD8348-EVAL, respectively.
