    Help ADS Document for MMIC PA Design

    Discrete OR MMIC OR RFIC, no matter Technology/Process you've been using, the Main Principles of Designing of an Power Amplifier are always same. There are some different tricks or methods but they are essentially same.

    Sensitivity of RF receiver front-end

    If you BER Meter, you can easily measure this Frontend. Sensitivity is a measure of Acceptable BER @ Signal Level. For instance, you define BER as 1.10^-3 then you decrease the Signal Level and when BER reaches/drop down to this level, this will be the Sensitivity at the same time. SNR is also...

    IP_2 (transistor parameters, amplifier configuration)

    You can't calculate IPn without Nonlinear Model.S-Parameters carry NO information about Nonlinearity. Essentially, you cannot calculate ANY kind of Nonlinearity of an Active Device since you don't know the Degree of Nonlinearity , you can just simulate with a given Nonlinear Model in a serious...

    SOT223 with 1.1W dissipation and gap pad to its plastic case top?

    For Silicon, in order to prevent a failure, in otherwords having a reasonable MTBF, the Junction temperature shouldn't exceed +85 degree. If I were you, I'd use DPAK Case instead of SOT-223.

    how to design new coupler block to AWR?

    Connect a small series resistance ( 0.01 Ohm). That's the trick..

    how to design new coupler block to AWR?

    Mr. EDA_Chandler, This Directional Coupler is a reciprocal element so you can use ANY Port as Input or Output since the s-parameter transfer matrix is given. There is no restriction on Passive AND Reciprocal Circuit elements. If you have paid attention, you will clearly see that the Matrix is...

    Plotting noise figure (NF) versus nFET current density in Cadence (current on log scale)

    Bias the MOS Transistor with an appropriate VGS voltage (must be higher than VGS(th) and Drive this transistor with a Constant Current Source thru Drain Side than change this current and plot NFmin vs. IDS

    how to design new coupler block to AWR?

    There is an element that you're potentially looking for.

    how to design new coupler block to AWR?

    "Couplers" have always 4 or more ports. If you don't want to use Coupled and Isolated ports, simply terminate them with 50 Ohm.

    TLIN (ADS) equivalent model in CADENCE VIRTUOSO

    To my knowledge, there are Transmission Lines in RF Library. But this library is not installed by default, you should install it manually.

    gpdk width not adjustable

    Is this PDK compatible with your Cadence ADE version ? It seems to me an incompatibility issue. Because ADE does not recognize MOS parametric entries. You should maybe enter these parameters without units because "M" stands for "Mega", not "meter".

    Interdigitated Electrode Capacitor

    As I have said before, I'm newbie to HFSS and I dont' want you to mislead. You can verify/compare this result by theoretical calculation.

    Interdigitated Electrode Capacitor

    I'm new to HFSS ( trying to learn ) but Modal Network is fine for this type of Planar Devices. HFSS Hybrid and Arrays solution type is also used in different type planar problems. 1703714061 I have used HFSS Modal Solution and found this Z11 ( Source is Circuit Port ) That's equivalent to...

    LNA DESIGN AND SIMULATION

    First, 60dB Power Gain is pretty pretentious. Even it will be implemented as RFIC, serious stability problems will occur and prediction of these potential stability problems will not be very predicted. The problems that you face to face are "General Design Challanges" and the Foundry should...
