General Description

The MAX2385/MAX2386 evaluation kits (EV kits) simpli-
fy evaluation of the MAX2385/MAX2386. The EV kits
allow the evaluation of the CDMA and GPS low-noise
amplifiers (LNA), as well as the CDMA and GPS down-
converter mixers, without the use of any additional sup-
port circuitry. The signal inputs and outputs use SMA
connectors to simplify the connection of RF test equip-
ment.
The MAX2385/MAX2386 EV kits are assembled with an
associated IC and incorporate input and output match-
ing components optimized for RF frequencies from
832MHz to 870MHz and an IF frequency of 110MHz.
