Lexiwave's LW107 is an integrated circuit used in pocket and portable mono radios. It is used with minimum external components with small size. The circuit employs a frequency-locked-loop (FLL) system to perform automatic channel searching. Selectivity is achieved by active RC-filter with Intermediate Frequency (IF) of about 70 KHz. Noise due to de-tuning and weak input signal is suppressed by the mute circuit.
