发明名称 TUNING APPARATUS
摘要 A tuning apparatus (100) compensates for temperature-related frequency variations of a filter (130). According to an exemplary embodiment, the tuning apparatus (100) includes an RF signal source, a tuner (110), and the filter (130). The tuner (110) includes a local oscillator (120) and is coupled between the RF signal source and the filter (130) and provides an IF signal for the filter (130). The tuner (110) also includes a frequency adjustment mechanism (126) for adjusting the frequency of the local oscillator (120) in response to a temperature characteristic of the filter (130).
