AN9614 - Using PRISM-Chip

Datasheet Summary

Description

A.

The band pass filters shown between the HFA3624 and the HFA3724 labeled as BPF1a and BPF1b on Figure 1 are centered at IF and filter the spread wideband waveform before demodulation on the receive side and before the final upconversion on the transmit side.

www.DataSheet4U.com Using the PRISM® Chip Set for Low Data Rate Applications Application Note January 1997 AN9614.1 Authors: Carl Andren and John Fakatselis Introduction The PRISM chip set has been optimized to address high data rate applications with up to 4 MBPS data rates. The PRISM can also be utilized for low data rate applications. To implement low data rate applications (below 250 KBPS) the designer needs to address design considerations in the following areas: ™ Description A. External IF Filtering The band pass filters shown between the HFA3624 and the HFA3724 labeled as BPF1a and BPF1b on Figure 1 are centered at IF and filter the spread wideband waveform before demodulation on the receive side and before the final upconversion on the transmit side.
