A very short written test (about 3 or 4 questions). 2 or 3 Ohm's Law questions, (Very Easy). Series Circuit to solve current, voltage drops and a voltage divider question. 1 RF question. Diagram with a 24dbm input through a coupler with a 3 Dbm loss. What is your output? Don't be over-concerned if you don't know the answer. They will help and explain.
They explained me before the kind of work they are doing and the nature of the projects on which they are working, in there interview they wanted to know how much I know about it.
If a radio breaks what do you do to fix it?
about what you would do differently in T Mobile, for example to reduce churn.
Experience with this type of work.
Software and fundamental communication and RF questions
Niquist theorem, Noise figure, Aliasing, Return Loss, RBW of spectrum analyser, Smith chart, Walsh code, Fourier Transform, IIP3 and some questions on resume.
non linearity of the divider in the sigma delta fractional N PLL.
questions regarding Smith charts, IIP3, cascaded NF. Issues with superheterodyne and direct conversion mixers
Why 50 ohms is standard in RF?
