IF FILTER : Ceramic filter, CFWCA450KGFA-R0 (Murata Manufacturing Co., Ltd., Japan)

Measurement condition

“Condition1” is the condition for the case of IF input :

IF SW

: in the A position.

IF IN input signal : input frequency(fif) = 450kHz, input level(VinIF)= 60dBuVEMF,

modulation frequency(fmod)=600Hz, deviation fdev=±2kHz

“Condition 2” is the condition for the case of Mixer Input :

IF SW

: in the B position

MIX IN input signal: input frequency(fmix)=21.7MHz, input level(VinMIX)=60dBuVEMF,

modulation frequency(fmod)=600Hz, deviation fdev=±2kHz

OSC(E)input signal: input frequency(fosc)=21.25MHz, input level(VinOSC)=105dBuVEMF
