Abstract
A frequency synthesized multi-band receiver having a phase locked loop (PLL) including a voltage controlled oscillator (VCO) for producing the local oscillator frequency. The PLL includes a programmable divider for dividing the output of the VCO for comparison with a reference frequency in a phase detector to produce a voltage for controlling the output frequency of the VCO. Memory means are provided for storing information concerning the upper and lower frequency limits of the bands over which the receiver is to operate.
