Description
Antennas are much shorter than quarter wavelength impedance obtained is
very small and highly dependent on the frequency. It was a difficult
game impedances over a decade of frequency coverage. Instead, the phase
of the input source-follower FET Q1. A high impedance input successfully
bridges Antenna characteristics at any frequency.
transistor Q2 is used as a follower, to provide a high impedance load for Q1, but more importantly that it makes to drive low-impedance amplifier coupled to commonly Q3, which each receive a voltage amplifier. Q3 Q4 turns transistor output impedance is relatively low in impedance, which is enough to drive 50 Three dimensional receiver, Antenna input impedance.
