ABSTRACT:
An electronic circuit including a frequency-selective part including a piezoelectric crystal and an inductance; The crystal is shaped relative to its crystal axes in such a way that its temperature coefficient and the temperature coefficient of the inductance have opposite signs in order to reduce the influence temperature on the pulling range of the frequency-selective part of the circuit.
