Maxim MAX2338 Manuals

MAX2338 EV kit is a MAX2338 evaluation kit that can simplify the evaluation of MAX2338. This kit supports single supply operation and includes all critical matching components.

The MAX2338 evaluation kit simplifies evaluation of the MAX2338 dual-band, triple-mode LNA and mixers. It includes 50Ω SMA connectors for all RF and IF input and output signals. Supports +2.7V to +3.3V single supply operation, and includes all critical matching components.

The MAX2338 is a dual-band CDMA cellular phone receiver RF front-end IC designed by Texas Instruments, and it 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. The MAX2338 includes a low-noise amplifier (LNA) with an adjustable high-input third-order intercept point (IIP3) to minimize intermodulation and cross-modulation in the presence of large interfering signals. For cellular band operation, a low-gain LNA is available for higher cascaded IIP3 at lower current. The CDMA mixers are designed for high linearity, low noise, and differential IF outputs. The FM mixer is designed for lower current and single-ended output. The MAX2338 triple-mode LNA/mixer includes an on- chip LO frequency divider to allow the use of a single VCO for both bands. This device is available in an ultra- small 28-pin leadless QFN package.
