• HMC252A RF port DC connection

    Hello,

    Is it possible to connect HMC252 RF output port directly to GND?

    Thanks and best regards.

  • HMC252A多余引脚处理问题

    需要使用RF开关芯片HMC252A的RF1、RF2、RF3通道。RF4、RF5、RF6通道该如何处理?直接悬空还是接地?

  • RE: HMC252A_input_1dB_Compression

    Hi,

    We have P1dB test data down to 100 MHz for HMC252A. As shown in the plot below, HMC252A degrades power compression below ~300 MHz of which is a normal characteristic of GaAs switches.

    HMC252A has typical P1dB of 26-27 dBm at 100 MHz. Considering production…

    Thank you for your reply.

    1. The current of VDD, A, B and C is 6.43mA, 55uA, 55uA and 1.6-1.8mA, respectively. Based on the datasheet, the current of C is not correct. It's too large and always changing.

    2. When I removed the DC blocking capacitors…

  • RE: AD9361接收6端差分和12路单端,数据手册上写3GHz性能会下降

    可能您没理解我的意思,我要搭建的就是AD9361内部,我是看了9361芯片内部的框图,然后自己搭建一下,我现在在搭建9361内部的接收通道,对于接收通道,6路差分12路单端,两个独立通道,我是用两个射频开关,所以我在ADI官网上找了一些射频开关,因为9361接收分为两个独立通道,所以一通道是3差分6单端,然后我选用了HMC252A,SP6T,唯一我认为不满足的是0-3.5GHz,但是AD9361工作范围是56MHz-6GHz,然后我又去找了SP8T,8选1的,他控制输入是正5V或者负5V,对于ADI公司成品的板子…
