MAX2370 Evaluation Kit
General Description
Features
ꢀ 50Ω SMA Connectors on All RF Ports
ꢀ BNC Connectors for Baseband Inputs
ꢀ Fully Assembled and Tested
The MAX2370 evaluation kit (EV kit) simplifies the test-
ing and evaluation of the MAX2370 quadrature trans-
mitter. The EV kit provides 50Ω SMA connectors for all
RF inputs and outputs. A varactor-based tank circuit is
provided for the on-chip IF voltage-controlled oscillator
(VCO) and phase locked with an on-chip PLL. I/Q base-
band inputs come with standard BNC connectors.
ꢀ Low-Power Shutdown Mode
ꢀ SPITM/QSPITM/MICROWIRETM Compatible
The EV kit allows evaluation of the MAX2370 I/Q modu-
lator, IF VGA, RF upconverter, IF VCO, dual synthesiz-
er, 3-wire programming interface, and power-manage-
ment features.
