Spurious reception

Ratio between sensitivity for an

unwanted frequency to the

sensitivity in the wanted channel.

The signal source is swept over

all frequencies 100 MHz ñ 2 GHz.

Signal level for BER = 10 3.

102.4 kHz channel filter

bandwidth.

LO leakage, 433/868 MHz

<-80/-66

dBm

VCO leakage

-64

dBm

VCO frequency resides between

1608 ñ 1880 MHz

Spurious emission, radiated CW

9 kHz ñ 1 GHz

1 ñ 4 GHz
