Abstract:
A wireless transceiver that receives a signal, the wireless transceiver comprising:a motherboard; an integrated substrate that is mounted on the motherboard; a switching circuitry that receives the signal; a surface acoustic wave filter die that receives the signal from the switching circuitry and that filters the signal; a low noise amplifier die that receives the signal from the surface acoustic wave filter die and that amplifies the signal; and a mixer die that receives the signal from the low noise amplifier die and that downconverts a frequency of the signal, wherein each of the switching circuitry, the surface acoustic wave filter die, the low noise amplifier die, and the mixer die is mounted on the integrated substrate; and the surface acoustic wave filter die is mounted in a flip chip configuration on the integrated substrate, and a passivation layer is deposited on the surface acoustic wave filter die prior to the surface acoustic wave filter die being mounted on the integrated substrate.
