Schematic diagram of the MAX2338 hp at the sound amplifier

By admin | Published: 01/02/2010
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. The includes a low-noise amplifier (LNA) with an adjustable high-input third-order intercept point (IIP3) to [...]

Schematic Diagram hp – MAX2338 Mixer IF SAW Filter Match at 183.6MHz for CDMA

By admin | Published: 01/01/2010
The design and simulation of the impedance match between the MAX2338 mixer stage and a 183.6MHz SAW filter in a CDMA application. The SAW filter S-parameter is used to simulate the interface with the mixer. A worked example is provided with a SAWTEK 855893 SAW filter. An optimum impedance matching circuit between the MAX2338 mixer differential [...]
