An embodiment is directed to a zero IF down converter circuit. The circuit comprises a voltage-to-current converter, a mixer, and a suppression circuit. The voltage-to-current converter converts an RF voltage signal to an RF current signal. The mixer changes the frequency of the current signal to a lower frequency current signal. The suppression circuit removes a lower frequency distortion component from the RF current signal before sending the RF current signal to the mixer.

A tunable oscillator having a tuning voltage input includes an inductor, and first and second varactor pairs arranged with the inductor to generate a signal having a frequency responsive to a tuning voltage applied to the tuning voltage input, each of the varactor pairs having a bias voltage input that may be controlled independently of the other varactor pair. The first varactor pair may be biased such that its capacitance varies substantially linearly with the tuning voltage over a first portion of the tuning range, and the second varactor pair may be biased such that its capacitance varies substantially linearly with the tuning voltage over a second portion of the tuning range.

The invention relates to the field of LCDs, and more particularly to an LED lightbar for a backlight module, and a backlight module. The front face of the LED lightbar is provided with LED lights, and the back face of the LED lightbar is a plane used for the sticking of a thermal conductive adhesive; the back face of the LED lightbar is provided with positioning edge(s) used for positioning the thermal conductive adhesive, and the positioning edge(s) is protruded from the back plane of the LED lightbar. The back face of the LED lightbar for a backlight module of the invention is provided with positioning edge(s) used for positioning the thermal conductive adhesive, and the positioning edge(s) is protruded from the back plane of the LED lightbar. When sticking the thermal conductive adhesive, the operator can align the thermal conductive adhesive with the edge of the positioning edge(s) to tidily stick. If being tidily stuck, the thermal conductive adhesive is tightly matched with the LED lightbar. Because the thermal conductive adhesive is not pulled to be straight, the inward pulling stress is avoided. Thus, even under severe conditions, the adhesive failure and deformation are not easily generated, and the stability and heat dissipating effect of the backlight module are guaranteed.
