Hi,

The datasheet is not clear how to configure the HMC1044 and it's not very easy as this chip is write only.

Description of SPI link with 9 bits data, 4 bits reg_addr and 3 bits chip_addr :

I think…

Hi,

Where can I find the s2p files for the HMC1044 tunable filter?

Hi,

I am using HMC1044 in one of my application. Using STM32F417 controller to configure HMC1044 through its SPI. 

I tried with 1MHz to 20Mhz as SPI clock but not able to configure HMC1044. What is the supported SPI clock frequency ? in data sheet I see…

Hi,

I noticed the frequency range of CN0507 is determined by the low-pass filters (HMC1044) and the directional couplers. The hardware should work up to 6GHz, if I replace HMC1044 with another filter up to 6GHz and replace BDCN-14-342+ with another coupler…

此次在线研讨会阐释了自收购Hittite Microwave后ADI的全新及扩展的RF能力。我们会举例说明ADI涵盖的更宽频谱范围及其真DC的重要性。信号链外的性能同样至关重要，展示低噪声、高稳定性控制和电源元件如何改善总体RF信号性能，并将讨论完整的信号链示例。

主要讨论天线到比特和比特到天线，信号链覆盖，即刚才提到的从真正的DC 0 Hz到110 GHz的频谱覆盖。 我会简要介绍其中涉及到的各类设备。

为什么良好的RF需要良好的电源，大家知道，RF需要干净的电源。然后，最后会和大家讨论“不止是芯片…

天线到数字以及数字到天线……ADI凭借领先的射频技术能力、系统知识与工艺技术，提供直流到90 GHz以上、涵盖整个RF信号链最丰富多样的RF IC组合。
