The decision circuit of the chip is applied with a DFF using SCFL structure and its tuned phase shifter with differential current amplifiers according to the principle of vector addition.
In general the circuit topology of multi-tuned filter consists of one series branch and multi-parallel branches.
多调谐滤波器在电路拓扑结构上通常由一个串联支路和多个并联支路组成。

As the amplifier tuned load circuit, they are able to select the base component cosine pulse to obtain undistorted amplification signal output, so this amp is also known as tuned power amplifier.
