I find it hard to find S-param model for Aluminum Electrolytic Capacitor.
Anybody tried modelling this CAPS in MWO? I'd like to have its Impedance over frequency response.
hi biff44,
i could not see any spur or oscillation in the spectrum analyzer even at -80 noise floor.
however on my setup of small signal S-parameter in vector analyzer, mu seems to be <1 on some frequencies which should indicate some instability, right?
in that sense, any tips or suggestions...
please see the picture below for the package
another thing i notice is with the amplifier DC turned-on (no RF input) @ Idq=400mA, when i connect a 50-ohm RF cable (hanging, no termination) at the output SMP port, the Idq increases to around 1040mA (cable length=320mm). At 270mm cable length...
hi mariana,
thanks for the response.
the transistor is an LDMOS plastic package with 2 die transistors inside. their common source are internally connected to its ground flange.
To our RF experts,
Kindly share your experiences on this: I did a MWO simulation for a 20W UHF broadband amplifier (470MHz to 900MHz). The simulated linear gain is around 17 to 19dB. Available test eval board of the transistor in standard Push-pull class AB config has a gain of around the same...
The broadband open circuit can be a reversed-bias PIN diode, right or maybe you have other recommendations on steering a phase shift from -40 to 40 degrees
I have a broadband input range. I would like to terminate it with a length of ope-circuit transmission line whose angle can be rotated from say -30 degrees to +30 degrees. What's the best solution you recommend for this phase shifter?
Hello,
My goal is to have a circuit that is broadband OPEN, with a variable phase angle from say 40 degrees to -40 degrees.
How will you do this with inductor and capacitor?
