  Not how big, but what is the principle will use. A tunable detector
will work different than a wide band detector. There are plenty wide
band detectors covering from 100KHz to 1GHz or from 50 MHz range up to
7GHz and up to -60dBm detection range. Look at AD and Linear
Technology sites.
If you need a doppler effect microwave detector this is different.
