www.qsl.netUsually a larger resonator will have a higher Q (e.g. a quarter wavelength coaxial resonator). • Choose an active device that has a low flicker corner frequency. A bipolar transistor biased at a low collector current will keep the flicker corner frequency to a minimum, typically around 6 to 15 KHz (Most semi-conductor

The electrical size of the antenna is measured by its ka value, where k is the wavenumber ( k = 2 π / λ , λ = wavelength at the operating frequency) and a is the radius of the smallest sphere that circumscribes the antenna. Antennas are considered to
