    Microwave Amplifier design

    You need S2p parameters of the devices. Select rftool in matlab and load the input matching circuits,device S2p file and output matching circuits into the rftool. Then see the response at your required frequency. It is very easy to simulate but you need strong fundamentals abt the amplifiers.

    FM (wireless) Sensitivity and NF?

    For FM radios the least SINAD generally consider as 12dB. So you can use this value in the same formula. Care muste be taken as the bandwidth should be the demodulated bandwidth. For example voice it should be 1KHz. I think r u got it.

    How to Find the carrier on spectrum analyzer?

    Re: How to Find Carrier Set the centre frequency of the spectrum analyzer into your desired frequency, press trace button on the front panel menu. you will get a required frequency with some other frequencies, Use peak search marker. Then you get the required carrier freuquency.

    Dipole Antenna Design

    antenna dipole design Dipole antenna is for Low frequencies, 900MHz and 1800MHz the antenna become too much bulk. So go with omni directional antennas.
