移動無線機。 In a frequency synthesizer type mobile radio, there are two types of fused locked loops (hereinafter referred to as PLLs) that generate the first local oscillator signal in the receiving section.
A local switching switch controlled by a control unit is provided on the output side of the LL and on the output side of the other PLL.
Fix L to the main channel, arbitrarily vary the frequency of the other PLL, and use the local oscillator switch to
A mobile radio device characterized by having a function of switching different types of PLL.
