Title:
RADIO FREQUENCY CHIP WITH RC CIRCUIT INTEGRATED ON CHIP
Document Type and Number:
WIPO Patent Application WO/2022/088299
Kind Code:
A1
Abstract:
A radio frequency chip with an RC circuit integrated on chip. The radio frequency chip comprises a substrate (100), an epitaxial layer (101), and an active area disposed on the epitaxial layer, wherein on the epitaxial layer, a plurality of sets of resistor-capacitor combined structures (60) are arranged between a gate electrode (40) of the active area and an input metal pad (50); resistors and capacitors of the resistor-capacitor combined structures (60) are connected in parallel; and the gate electrode (40) of the active area is connected to the input metal pad (50) by means of the resistor-capacitor combined structures (60). According to the radio frequency chip with an RC circuit integrated on chip, an RC circuit is integrated inside the chip, thereby improving the gains and robustness of a radio-frequency power device at a low frequency and a high frequency.
