SL623 General Description

The SL623C is a silicon integrated circuit combining the functions of low level, low distortion AM detector and AGC generator with SSB demodulator It is designed specially for use in SSB/AM receivers in conjunction with SL610C,SL611C and SL612C RF and IF amplifiers. It is complementary to the SL621C SSB AGC generator.

The AGC voltage is generated directly from the detected carrier signal and is independent of the depth of modulation used Its response is fast enough to follow the most rapidly fading signals When used in a receiver comprising one SL610C and one SL61 2C amplifier, the SL623C will maintain the output within a 5dB range for a 90dB range of eceiver input signal.

The AM detector, which will work with a carrier level down to 100mV, contributes negligible distortion up to 90% modulation. The SSB demodulator is of single balanced form.

The SL623C is designed to operate at intermediate frequencies up to 30MHz. In addition it functions at frequencies up to 120MHz with some deg radation in detection efficiencies
