BPF for Mixer System Application
The RF Front End devices are used in a wide variety of RF products and applications. RF Front End (RFEE) is the circuitry used between antenna and RF transceiver.
The RF Front End consists of:
- Band pass filter to receive signal from antenna and remove unwanted noise from circuit
- RF amplifier to amplify weak signal
- local oscillator to generate a stable radio frequency signal
- mixer to convert signal frequency
In a RF receiver front end, the RF signal needs in a down conversion mixer to a lower intermediate frequency (IF). On the contrary, in a RF transmitter front end, the intermediate frequency signal needs in a up conversion mixer to RF signal.
In communication systems of the RF Front End circuit, RF band pass filters occupy an important position. Band pass filter can remove signal interference and purify the signal in circuit. Temwell has long history with the design and manufacture of helical band pass filters. The helical band pass filters provide low loss, good performance and highly selectivity for RF Front End application.
