• HMC1049


    I'm interested in the HMC1049. I would like to know if the device can opperate down to 10 Mhz. and if you have any data on the noise figure between 10 and 300Mhz.?  Thanks.

    Best Regards.

  • HMC1049

    Hi, I am using HMC1049LP5E. The RF input is DC coupled. What is the  maximum DC bias  voltage can I apply to the FR input pin. Can I use ACG3, ACS2 pins to DC bias HMC1049?

  • RE: I want to use the HMC920LP5E Active Bias Controller with the HMC1049LP5E LNA.


    Yes you can use HMC920 to bias HMC1049. HMC1049 is released after HMC920, and the list on HMC920`s datasheet is not updated continuously; hence HMC1049 is missing on that list.

    We do not have the values calculated, but the formulas on the datasheet…

  • RE: hmc-980

    Yes, HMC1049 can be biased with HMC980. We do not have a ready apps circuit drawing though. But we have one for biasing HMC1049 with HMC981, see attached. The idea is the same. HMC981 is the lower current version of HMC980.



  • RE: 100MHz to 4000MHz LNA

    Other options to consider might be HMC460 (dc-20 GHz, 2.5 dB nf) and HMC1049 (300 MHz to 20 GHz, 1.7 dB NF).

  • RE: HMC1049 Pulsed operation


    Based on HMC1049 datasheets, CW maximum input power is 18 dBm.

    We have not done any pulse tests therefore we can not guarantee beyond 18dBm of input power regardless of pulse duration.

  • HMC341 die

    Where can I get the S parameter of LNA HMC341 measured on die? The S papameter offered on website is the results measured on test board.

  • Die Temperature

    How can I determine the die temperature of your device?

  • HMC392A-Die

    I wanted to Simulate the HMC392A in Microwave office. So i downloaded its S2P file from design resources and as i performed simulation its responses like return loss is better than the datasheet but its gain is decreased to max15.7 dB after simulation…

  • HMC598 Die


    Do you have a maximum power consumption for the HMC598 in die form? The data sheet shows 175 mA @ 5 volts, but it's only a typical number and I'm seeing  220 mA @ 5volts, with no input signal or output load. Thanks.

    Best Regards.
