In communication equipment, RF signal processing unit is responsible for sending and receiving signals, including RF transceiver, antenna, RF front end, etc. Among them, the RF front-end is composed of a series of components, including power amplifier (PA), filter, Switch, Diplexer/Duplexer (composed of two Filters), low noise amplifier (LNA), respectively corresponding to different RF signal processing functions. Today we’re going to talk about RF filters.

(1) Definition

In the radio frequency/microwave system, it is usually necessary to separate several useful frequency signals from the signal spectrum and filter other useless frequency signals. The equipment to complete this function is called the filter. Rf/microwave filters are filters in the RF and microwave frequency bands in the passband range.

Filter is a key RF component in wireless communication system.

Filter the mirror frequency interference, attenuation noise, frequency division multiplexing

Used for high performance oscillating, amplifying, frequency doubling, mixing circuit

Effective wideband impedance matching networks and coupling structures

(2) Classification

Working attenuation LA is usually used to describe the amplitude characteristics of filters.

1. According to attenuation characteristics

The low-pass filter allows the low-frequency signal to be transmitted from the input port to the output port with a small attenuation amount. When the signal frequency exceeds the characteristic cutoff frequency, the attenuation amount of the signal will increase sharply, so that the signal amplitude of the output port will decrease

The high-pass filter has the opposite characteristic. When the signal frequency exceeds a specific cutoff frequency, the signal is transmitted from the input port to the output port with a small amount of attenuation.

Band-pass and band-stop filters are defined by a specific lower and upper frequency band, in which the signal attenuator has either low (band-pass) or high (band-stop) attenuation relative to other frequency bands.
