Abstract

The invention discloses a radio frequency front-end module applied to 5G N77 and N79 frequency bands, and relates to the technical field of radio frequency front ends. The radio frequency front-end module comprises a radio frequency switch which is used for controlling the radio frequency front-end module to receive or transmit signals from or to an antenna; and an integrated passive device filter (IPD) used as an on-chip radio frequency filter and used for selecting frequency bands at a radio frequency receiving front end and inhibiting or blocking signals outside the required frequency bands. The radio frequency front-end module can work in a receiving (RX) mode and can also work in a transmitting (TX) mode through the N77 and N79 frequency bands, when the radio frequency front-end module works in the RX mode, the IPD filter integrated into the chip performs frequency band selection, then the low-noise amplifier amplifies a radio frequency signal. Te radio frequency front-end module is high in integration level, and has the capabilities of selecting working frequency bands and amplifying low noise, reduces the occupied area and volume of a radio frequency front end, and is wide in application range, safe and reliable.

Description

technical field [0001] The invention belongs to the field of radio frequency front-end technology, in particular to a radio frequency front-end module applied to N77 and N79 frequency bands. Background technique [0002] With the popularization of smart mobile terminals and 5G technology, in order to realize complex functions in a compact space, highly integrated solutions are required. The RF front-end module is a key part of the smart mobile terminal, which is used to receive and transmit signals. Traditional RF front-end modules often use off-chip RF filters. The filters used in mainstream mobile terminals include SAW filters, BAW filters and FBAR Filters, SAW filters are best suited for frequencies lower than 1.5GHz, BAW filters and FBAR filters have a high degree of monopoly and high process costs, while integrated passive device filters are applied to mature and advanced manufacturing processes, with small area and volume , high performance and good consistency.
