... Rev 2; 4/03 Triple/Dual-Mode CDMA LNA/Mixers General Description The MAX2338 receiver RF front-end IC is designed for dual-band CDMA cellular phones and can also be used in dual-band TDMA, GSM, or EDGE cellular phones. Thanks to the MAX2338’s on-chip low-power LO divider, the cellular VCO module can be eliminated. ...

... Triple/Dual-Mode CDMA LNA/Mixers Detailed Description The MAX2338 consists of cellular band and PCS band (LNAs) and mixers. The IC also consists of a local oscillator (LO) divider and LO buffers for cellular and PCS bands. Low-Noise Amplifiers The MAX2338 LNAs’ gain and linearity are switched by the GAIN and LIN input, respectively ...

... The LNA and mixer design optimizes cascaded perfor- mance in all gain and linearity modes. In HGHL mode both the LNA and mixer have a low noise figure, high gain, and high linearity. The LNA has high gain to mini- Table 2. MAX2338 Cellular Band LNA S-parameters High-Gain, High-Linearity Mode | | FREQUENCY (MHz) ...

... At the digital mixer outputs, keep the differential signal lines together and of equal length to ensure signal balance. For best gain and noise perfor- mance, solder the exposed paddle evenly to the board ground plane. Table 3.
