Abstract

The receiver for various frequency bands has only one oscillator (OSZ), which is followed downstream by a frequency divider having a settable real divisor value. For generating the real divisor value, this frequency divider in turn has a multiplier with a settable integral multiplier value (M1) and a divider, downstream of the multiplier, with a settable integral divisor value (N1).
