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