Detailed Description
Modes of Operation
The modes of operation for the MAX2837 are clock-out,
shutdown, transmit, receive, transmitter calibration, and
receiver calibration. See Table 1 for a summary of the
modes of operation. The logic input pins—ENABLE (pin
25), TXENABLE (pin 47), and RXENABLE (pin 48)—con-
trol the various modes. When the parts are active, vari-
ous blocks can be shut down individually through SPI.
Shutdown Mode
The MAX2837 features a low-power shutdown mode.
Current drain is the minimum possible with the supply
voltages applied. In shutdown mode, all circuit blocks
are powered down, except the 4-wire serial bus and its
internal programmable registers. If the supply voltage is
applied, the registers are loaded and retained.
Standby Mode
The standby mode is used to enable the frequency syn-
thesizer block while the rest of the device is powered
down. In this mode, PLL, VCO, and LO generator are on,
so that Tx or Rx modes can be quickly enabled from this
mode. These and other blocks can be selectively
enabled in this mode.
Receive (Rx) Mode
In receive mode, all Rx circuit blocks are powered on and
active. Antenna signal is applied; RF is downconverted,
filtered, and buffered at Rx BB I and Q outputs. The slow-
charging Tx circuits are in a precharged “idle-off” state
for fast Rx-to-Tx turnaround time.
Transmit (Tx) Mode
In transmit mode, all Tx circuit blocks are powered on.
The external PA is powered on after a programmable
