IF2 Amplifier Chain
The 10 nF capacitors cut the DC response. The first network has the low cut-off frequency and the sec-
ond network the high cut-off frequency.
The input impedance of the IF2 amplifier is 1700Ω. This value permits use of popular filters with an
impedance between 1500Ω and 2000Ω. The IF2 amplifier is directly connected to the FSK demodulator.
The bandwidth is internally limited to 1 MHz to minimize noise entering the discriminator.
The IF2 amplifier acts like a band pass filter centered at 455 kHz with capacitive coupling between the
different stages of the amplifier and mixer. The total voltage gain is typically 86 dB. Thanks to the capac-
itive coupling, no slow DC feedback loop is needed, thus enabling the IF2 amplifier to be activated
rapidly. IF2DEC must be decoupled with at least 2.2 nF.
