Connections Setup
This section provides step-by-step guide operating kits testing devices' functions. turn power signal generators until connections made. Testing jumpers desired mode according Table Table Connect supply (preset 2.75V) terminals (through ammeter, desired) kit. generator spectrum analyzer operate frequency 881MHz cellular, 1960MHz PCS, 1575.42MHz power level -30dBm. Connect output generator respective connector, connect coaxial cable from output connector spectrum analyzer. Turn supply activate generator's output. signal that appears spectrum analyzer should have magnitude approximately -15dBm high-gain mode. (Optional) Another method determining gain using network analyzer. This advantage displaying gain swept frequency band, addition displaying input output return loss. Refer user manual network analyzer setup details. Testing Mixer jumpers desired mode according Table Table Connect supply (preset 2.75V) terminals (through ammeter, desired) kit. generator output frequency 881MHz cellular, 1960MHz PCS, 1575.42MHz power level -30dBm. Connect output this generator respective mixer input connector.

second generator output frequency according Table connect input port (LO_IN). Connect coaxial cable from desired port connector spectrum analyzer. Table port jumper settings. spectrum analyzer center frequency 183.6MHz. Turn supply activate generators' outputs. signal that appears spectrum analyzer should have amplitude approximately -17dBm high-gain mode.
Layout
good board layout essential part circuit design. board serve guide laying board using MAX2351/MAX2354/ MAX2538. decoupling capacitor close device's minimize supply coupling. Proper grounding essential. Connect ground plane either directly through vias close possible. Keep traces carrying signals short possible minimize radiation insertion loss. Keep differential mixer output traces together equal length ensure signal balance. Solder entire bottom-side exposed evenly board ground plane proper device operation. input trace layer board avoid via-induced coupling. Minimize parallel traces improve coupling loss isolation. abundant ground vias between traces minimize undesired coupling.
