Communication ICs
FM IF detector for cordless phones
BA4116FV
The BA4116FV is an IC with mixing circuit, IF circuit, FM detector circuit, RSSI circuit, and noise detector circuit. As it
can operate at low voltages, it is ideal for use in cordless phones.
FApplications
Cordless phones, amateur short wave radios, and other portable wireless equipment
FFeatures
1) Input frequencies of 10MHz to 150MHz can be ac-
commodated.
4) High sensitivity; 12dB SINAD sensitivity = 8dBµVEMF
(50 Ω)
2) Low-voltage operation. (1.8 to 5.5V)
3) Excellent temperature characteristic.
5) High intercept point. (–11dBm)
6) Small package used. (0.65mm pitch)
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)

FDetermining the filter amplifier constant (multi-layer recovery band pass filter)
f0: Center frequency
Q: Center frequency f0 /band width BW
A0: I/O gain
The reference resistance R0 is determined as C1 = C2 =
C0.

R1 = R0 Q/A0
R2 = R0 /[2Q - (A0 /Q)]

R3 = 2R0
Q
The Filter gain can be adjusted by varying R1, but with the
A0 > 1 design, please be aware that influence from the
open loop characteristic of the amplifier causes offset in
the center frequency f0.
