Latest Patents

James G Haerle holds a patent for an "IF circuit with reduced sound attenuation for cable signals." This invention involves a cable-ready television receiver that includes a tuner switchable between cable and off-air signals. The design features an LC trap tuned to the audio carrier frequency, which is coupled between the tuner and a SAW IF amplifier. The trap incorporates a varactor diode that, when exhibiting a large capacitance, effectively disables the trap for cable signals. Conversely, when used for off-air signals, the voltage applied to the varactor diode causes it to exhibit a much smaller capacitance, enabling the trap and improving audio quality.
