Q: Explain the difference between DC-isolated and non-isolated transformers. A. A DC-isolated transformer is one that does not allow a DC current to pass between the primary and secondary windings. Q: Mini-Circuits transformers are tested with 50Ω systems. How do they...

Q. What is the effect of using a 50Ω amplifier in a 75Ω system? A. When a 75Ω load is seen from an ideal 50Ω amplifier or vice-versa, a 1.5:1 VSWR results which alters gain, output return loss, and gain flatness in real-life amplifiers. If active directivity...

Q. Many of MCL’s fixed attenuators are specified up to 1500 MHz. How will they perform at higher frequencies? A. With the exception of the 75Ω models, most fixed attenuators perform reasonably well above 2000 MHz. Please refer to data pages for actual...
