FIELD: radio engineering, communication.
SUBSTANCE: ladder-type reconfigurable filter is made on one board and contains two surface acoustic waves (SAWs) resonators, two inductance coils, two capacitors and two voltage variable-capacitance diodes. The outputs of the first voltage variable-capacitance diode, the first capacitor and the first SAW resonator are connected to each other and connected to the input potential terminal of the filter.
EFFECT: provision of the possibility to change the bandwidth of the filter and increasing the number of simultaneously operating bandwidths.
