  • LMH6521 ADS2009 Spice model setup

    Other Parts Discussed in Thread: LMH6521 I'm working on a design using the LMH6521 DVGA and I've been trying to setup a simulation using the ADS2009 spice model found at ( http://www.ti.com/product/LMH6521/toolssoftware ). I'm running ADS2009U1 and…

  • RE: Amplifiers forum

    Hi Rahul, 1. These HS Amps have ADS models already: LMH6523, LMH6881, LMH2832, OPA857, LMH6521, LMH6554, TRF37X73, and TRF37X75. Maybe you can use one of these in the meantime? I don't have good answers for your other inquiries. Hopefully they will be…

  • LMH6521 S2P Files

    Other Parts Discussed in Thread: LMH6521 Hi Team, Do we have measured s-parameters (s2p files) of the LMH6521 for its operation over frequency and gain (such as fig.4 in the datasheet), so I can model it for the system. Thanks, Max

  • LMH6521 - Serial Mode Not Responding

    Other Parts Discussed in Thread: LMH6521 Hello! I am using a LMH6521 to amplify a 125 MHZ signal. I have a custom board I am talking to with the SPIUS2 SPI controller. I have the CLK, CS, SDI, SDO connected between the SPIUS2 and the LMH6521 with a 470…

  • RE: LMH6517: Are there any restrictions to operating the LMH6517 with DC coupled inputs?

    Hello Ed, Here is a reference design on how to do this for the LMH6521: The same concepts will apply to this device, as it also features a self-biasing feature to 2.5V. In regards to signal overshoot, I would confirm that you are not exceeding the abs…
