You got my curiosity up. What is 90 MHz used for?

i want to check the output power of an fm transmitter, and i don't
have a wattmeter. most of the wattmeters available in market here have
a range of
0-50watt or 0-100 watt.
i want to design one, with a range of 0-2 watt approx,

design an fm
transmitter from scratch, given that "i need to transmitt an fm signal
at 90Mhz with an output power of 2 watt"

i
know it's illegal, and i am not going to cause any damage. i just want
to learn how to design. let me mention that i am very new to this
subject.

Anand-

You protest too much. This is a Ham Radio forum, so mention of a 90 MHz
transmitter is like waving a red flag. Few will believe that you don't
intend
to transmit with it.

Are really trying to learn, or are you trying to get us to do your
homework?
Measuring low power may be as simple as using a diode detector to measure
voltage across a 50 Ohm load, and calibrating the meter scale in watts.
As a
designer, you should be able to figure it out!

If you are serious, why not become a licensed Ham Radio operator, and
design
equipment that is legal to use? You can find a lot of interesting
information
at http://www.qrz.com, and even practice taking a Ham Radio exam at
