The MAX2310/MAX2314 evaluation kits (EV kits) simplify testing of the MAX2310/MAX2314 IF receivers. These kits allow evaluation of the devices' variable-gain amplifier (VGA), I/Q demodulator, dual-band voltage-controlled oscillators (VCOs), synthesizer, 3-wire programming interface and power-management features. Figures 1 and 2 show MAX2310 and MAX2314 kit schematics, respectively.
The EV kits provide 50Ω SMA connectors for all signal inputs and outputs. A varactor-based tank circuit is provided for the on-chip VCO and can be tuned by a potentiometer or an external voltage or phase locked with the on-chip phase-locked loop (PLL). PC board pads (J12, J13, J14, J15) are available for installing low-inductance oscilloscope probe points, if desired.
