inputs for the receiver and transmitter. If both inputs

are at logic 0, the part enters shutdown mode, and

the supply current drops below 1μA. When one input

is brought to logic 1, the corresponding function is

enabled. If RXEN and TXEN are both set to logic 1, the

part enters standby mode, as described in the Standby

Mode section. Table 1 summarizes these operating

modes.

Power-down is guaranteed with a control voltage at or

below 0.6V. The power-down function is designed to

reduce the total power consumption to less than 1μA in

less than 2.5μs. Complete power-up happens in the

same amount of time.

Standby Mode

When the TXEN and RXEN pins are both set to logic 1,

all functions are disabled, and the supply current drops

to 160μA (typ); this mode is called Standby. This mode

corresponds to a standby mode on the compatible IF

transceiver chips MAX2510 and MAX2511.

__________Applications Information

Extended Frequency Range

The MAX2411A 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, PA driver gain, and mixer conversion gain

are plotted over a wide frequency range in the Typical

Operating Characteristics. When operating the device

at RF frequencies 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 from that specified in the AC

Electrical Characteristics table, the IF, IF matching net-

work must also be altered. The Typical Operating

Characteristics provide port impedance data versus fre-

quency on all RF and IF ports for use in designing

matching networks. The LO port (LO and LO ) is internal-

ly terminated with 50 ? resistors and provides a VSWR of

approximately 1.2:1 to 2GHz and 2:1 up to 3GHz.

Layout Issues

A properly designed PC board is essential to any

RF/microwave circuit. Be sure to use controlled imped-

ance lines on all high-frequency inputs and outputs.

Use low-inductance connections to ground on all GND

pins, and place decoupling capacitors close to all V CC

connections.

For the power supplies, a star topology works well.

Each V CC node in the circuit has its own path to the

central V CC and a decoupling capacitor that provides a

low impedance at the RF frequency of interest. The

central V CC node has a large decoupling capacitor

as well. This provides good isolation between the

different sections of the MAX2411A. The MAX2411A

EV kit layout can be used as a guide to integrating the

MAX2411A into your design.
