AD8342: 有源接收混频器（低频至3 GHz）
AD8342是一款高性能、宽带有源混频器，非常适合要求严格的接收通道应用，这些应用要求所有端口均具有宽带宽，并且交调失真和噪声系数极低。AD8342的典型变频增益为3.7 dB，RF频率为238 MHz。集成的LO驱动器以低LO驱动电平提供50 Ω输入阻抗，有助于将外部元件数降至最少。差分高阻抗宽带RF端口很容易与有源器件和无源滤波器接口。RF输入接受高达1.6 V峰峰值或8 dBm（相对于50 Ω，P1dB）的输入信号。开集差分输出提供出色的平衡性能，可以与差分滤波器或中频放大器结合使用，例如 AD8370，AD8375，
The AD8342 is a high performance, broadband active mixer. It is well suited for demanding receive-channel applications that require wide bandwidth on all ports and very low intermodulation distortion and noise figure.The AD8342 provides a typical conversion gain of 3.7 dB with an RF frequency of 238 MHz. The integrated LO driver presents a 50 Ω input impedance with a low LO drive level, helping to minimize the external component count.
The differential high impedance broadband RF port allows for easy interfacing to both active devices and passive filters. The RF input accepts input signals as large as 1.6 V p-p or 8 dBm (relative to 50 Ω) at P1dB. The open-collector differential outputs provide excellent balance and can be used with a differential filter or IF amplifier, such as the AD8369, AD8370, AD8351, or AD8352. These outputs can also be converted to a single-ended signal using a matching network or a balun transformer. The outputs are capable of swinging 2 V p-p when biased to the VPOS supply rail.The AD8342 is fabricated on an Analog Devices, Inc., proprietary, high performance SiGe IC process. The AD8342 is available in a 16-lead LFCSP. It operates over a −40°C to +85°C temperature range. An evaluation board is also available.
