• ADRF5021's video feedthrough

    Dear Sir,

    Could you provide specification which is Video feedthrough for ADRF5021?

    Please refer this specification in ADG901 as below

    Thanks!

  • 求大神解惑

    目前项目设计需要用到高速开关,例如ADG901、ADG719的开关时间都在10nS以下,在实际实用中能否有什么方法使开关时间固定在某个值不变或变化在0.3nS以下?还是说开关时间最小也会有几nS的变化?

  • RE: Very Low-Capacitance LF Switches

    Hi Andrew,

    The ADG12xx series are our lowest capacitance and charge injection precision (DC + lower frequency) industrial range switches (i.e. +/-15V).  They are class leading. Note the capacitance is measured at the pin relative to ground.  The package…

  • RE: ADCMP572 spice model

    Hi Arthur,

    We are trying to build a specialized sample and hold circuit. The output from a detector (which has a voltage swing of ~150mV and a bandwidth of ~2.5 GHz) is passed through a Schmitt trigger (presumably using the hysteresis pin of the ADCMP573…

  • RE: Sample and hold circuit

    Hello Doug,

    I have already posted in the amplifier's forum for some of my comparator needs. I will re-post it here to give you a better idea of the project I have in hand.

    We are trying to build a specialized sample and hold circuit. The output from…

  • RE: Pulsing 2.4 GHz oscillator

    Dear Allan,


    I would recommend the ADF4360-0 as the base oscillator. It is very simple to use, but check if its phase noise meets your requirements.

    It is possible the turn off and on the output signal by switching the PLL to power-down mode, but it…

  • 开关与多路复用器常见问题解答

    1. 问:使用单电源工作时,ADG1612好像无法正常发射双极性信号。当信号降至地电压以下时,信号发生削波。如何避免这种情况?

    答:在器件采用单电源供电时,如果源极引脚或漏极引脚上的模拟输入信号降至基板电压(Gnd)以下,则内部ESD保护二极管将开始导通。发生这种情况时,您会看到,ON通道上发生失真或削波现象,OFF通道出现电流。另外,OFF开关可能处于导通状态。为关闭该开关,必须使Vgs < Vtn ( ~ 0.7v)。最低电压被施加到栅极(这里是GND)。然而,如果S/D降至栅极电压以下…

  • 技术大咖带你轻松解决ADG9xx宽带CMOS开关常见问题

    简介

    ADG9xx CMOS宽带开关主要设计用来满足工业、科研和医用(ISM)频段 (≥900 MHz) 信号发射器件的要求。这些器件具有低插入损耗、高端口间隔离度、低失真和低功耗等特性,因而是要求低功耗且能够处理发射功率 (最高达16 dBm) 的许多高频应用的理想解决方案。典型应用包括高速滤波和数据路由。

  • ADG918 Blocking of high amplitude signals

    I'm planning to use the ADG918 for multiplexing between two inputs. The ON path shall pass signals up to +/-0.5Vp which is nicely within the 7 dBm max. input spec. The OFF port may, however, be subjected to 20-40 ns spikes of up to +/-2Vp. My concern…
