*1 Value measured with untuned input.

*2 NF meter direct-reading value (DSB measurement).

*3 Value with a desired reception signal input level of −30 dBm, an interference signal of 100 kHz/30 % AM, and an

interference signal level where S/I=46 dB measuered with a spectrum analyzer.

*4 Value when the PLL is not operating.
