When the TXEN and RXEN pins are both set to logic 1,
all functions are disabled and the supply current drops
to 160µA (typical). This mode is called standby, and it
corresponds to a standby mode on the compatible IF
transceiver chips MAX2510 and MAX2511.
The MAX2410 has been characterized at 1.9GHz for use
in PCS-band applications; however, it operates over a
much wider frequency range. The LNA gain and noise
figure, as well as mixer conversion gain, are plotted over
a wide frequency range in the Typical Operating
Characteristics . When operating the device at RF fre-
quencies other than those specified in the AC Electrical
Characteristics table, it may be necessary to design or
alter the matching networks on the RF ports. If the IF
frequency is different than that specified in the AC
Electrical Characteristics table, the IFIN and IFOUT
matching networks must be altered. The Typical
Operating Characteristics provide Port Impedance Data

vs. Frequency on all RF and IF pins for use in designing
matching networks. The LO port (LO and LO) is internally
terminated with 50Ω resistors and provides a VSWR of
approximately 1.2:1 to 2GHz and 2:1 up to 3GHz.
A properly designed PC board is an essential part of
any RF/microwave circuit. Be sure to use controlled
impedance lines on all high-frequency inputs and out-
puts. Use low-inductance connections to ground on all
GND pins, and place decoupling capacitors close to all
V
For the power supplies, a star topology works well. In a
star topology, each V
path to the central V
tor which provides a low impedance at the RF frequen-
cy of interest. The central V
decoupling capacitor as well, to provide good isolation
between the different sections of the MAX2410. The
MAX2410 EV kit layout can be used as a guide to inte-
grating the MAX2410 into your design.
