• RF Switches DC PASS Characteristics: ADG919 BCPZ Voltage and Current Handling

    With many of the RF Switches that specify DC-2Ghz (or DC-___Ghz range) I am having difficulty understanding how MUCH DC they can pass from port to port.  Can these switches pass 6VDC with 120mA of current?  I am trying to use the RF SPDT switches to control…

  • bipolar dc bias on ADG918 or ADG919

    Hi,
    I was wondering what the limits for (quasi-) dc signals for the ADG918/919 switches are?

    Most importantly, is it ok to apply negative dc bias?
    Our application needs a switch for bipolar (±1.5V) time signals with a bandwidth of up to ~1GHz but also…

  • RE: Using multiple AD8232 to get multi-lead ECG

    Hello Prav,

    Sorry for the late response.

    I see from your image that you are trying to interchange LA and RL. May I know the reason?

    RL is a node dedicated for the Right Leg electrode which is used as a reference node.
    So I think RL should not be interchanged…

  • RF Switch required for Iridium Satellite Transceiver

    Hi, I need to switch an Iridium satellite transceiver between two identical passive antennas. The Iridium transceiver has the following specifications:

     

    Operating Frequency: 1616 to 1626.5 MHz

    Average Power during Transmission (Max): 38.45 dBm

  • RE: Some questions about ADG918

    Hi Wayne,

    It might be helpful for you to note the S11 data points for the ADG918 mentioned in the datasheet (in Table 1). This will give you data for what the return loss limits are for several frequency points when the switch is on and return loss data…

    Hi Radhika,

    Sorry for the delayed reply.  There was some issue with our notification system. 

    I have attached a document that shows our recommendation for applying the DC bias.  I think this will help you. 

    Regards,

    Eric.

  • DC Coupling HMC194A

    Hi,

    I am trying to use a pair of HMC194A devices dc coupled together. Internally these seem to be pre-biased to the supply rail, in this case +5V, and I understand from other enquiries that it is possible to do this. The problem I have is that in trying…

  • RE: Reflective switches

    The reflective switch is the same as the absorptive switch except the 50ohm shunt resistor is replaced by a 0ohm element.  The ADG902 (SPST), ADG919 (SPDT), ADG936R (dual SPDT), and the ADG904R (SP4T) parts are reflective switches.  A reflective switch…
