s: MAX2323/2325/2329. These are LNA/Mixer ICs optimized for CDMA applications in both cellular and PCS bands. The MAX2323 addresses dual-band, triple-mode CDMA applications by providing switched signal paths for cellular CDMA and PCS CDMA. The MAX2325 and MAX2329 are cellular-band dual-mode and PCS-band versions, respectively. This technical note is focused on how to determine the system specification of a CDMA receiver in order to establish a practical specification for a low noise amplifier and down converter. In the second section, the performance and features of MAX2323/25/29 are described in detail. The last section provides details of how to design the receiver front end, including designing matching circuits for RF and IF SAW filters to optimize performance of the receiver. A practical circuit and measurement data are shown in this note as well.
