LOW_POWER_ANTENNA_TUNER

Published:2009/6/15 21:15:00 Author:May | From:SeekIC

This antenna tuner is suitable for use with low-power (less than 5 W) transmitters or SW re-ceivers. 52 selects inductance and 52 connects the 365-pF capacitor to either the transmitter or the side of the inductor. The tiny tuner is comprised of a tapped inductor (L1) and a variable capacitor (C1), which is connected to the induc-tor through a center-off SPDT switch (S1). That switch arrangement permits the capacitor to be connected to either the input or the output of the circuit.
