  • Chip resistor with outrigger heat sink
    Patent number: 8994490
    Abstract: A surface mount chip resistor for increasing power handling capabilities of radio frequency (RF) circuits and for minimizing parasitic capacitance and inductance effects, the chip resistor includes a ceramic substrate having a main portion and an outrigger. A resistor element is between an input contact and an output contact on a top surface of the main portion. A ground plane attachment area is on a top surface of the outrigger. The ground plane attachment area is mounted to a ground plane of a circuit board to provide a heat pathway for dissipating heat generated by the resistor element.

  • Integrated hybrid-direct couplers
    Patent number: 8766742
    Abstract: An integrated coupler may vertically integrate a hybrid coupler and a directional coupler. The hybrid coupler may include a first quarter-wave metallic strip dielectrically coupled to a second quarter-wave strip. The directional coupler may include the second quarter-wave metallic strip dielectrically coupled to a third metallic strip. The first quarter-wave metallic strip may receive a first input signal. The second quarter-wave metallic strip may receive a second input signal, and it may superimpose the first quarter-wave metallic strip along a vertical space, so as to combine power received from the first input signal and the second input signal to form an output signal. The third quarter-wave metallic strip may superimpose the second quarter-wave metallic strip along the vertical space, so as to sample the output signal of the second quarter-wave metallic strip.
