The MAX2420/MAX2421/MAX2422/MAX2460/MAX2463 are highly integrated front-end ICs that provide the lowest cost solution for cordless phones and ISM-band radios operating in the 900MHz band. All devices incorporate transmit and receive image-reject mixers to reduce filter cost. They operate with to +4.8V power supply, allowing direct connection to a three-cell battery stack. The receive path incorporates an adjustable-gain LNA and an image-reject downconverter with 35dB image suppression. These features yield excellent combined downconverter noise figure (4dB) and high linearity with an input third-order intercept point to +2dBm. The transmitter consists of a variable-gain IF amplifier with more than 35dB control range, an image-reject upconverter with 35dB image rejection, and a poweramplifier (PA) predriver that produces to +2dBm (in some applications serving as the final power stage). All devices include an on-chip local oscillator (LO), requiring only an external varactor-tuned LC tank for operation. The integrated divide-by-64/65 dual-modulus prescaler can also be set to a direct mode, in which it acts an LO buffer amplifier. Four separate powerdown inputs can be used for system power management, including a 0.5A shutdown mode. These parts are compatible with commonly used modulation schemes such as FSK, BPSK, and QPSK, as well as frequency hopping and direct sequence spread-spectrum systems. All devices come a 28-pin SSOP package. For applications using direct VCO or BPSK transmit modulation, as well as receive image rejection, consult the MAX2424/MAX2426 data sheet. For receive-only devices, refer to the MAX2440/MAX2441/MAX2442 data sheet.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

25C guaranteed by production test, <25C guaranteed through correlation to worst-case temperature testing. Calculated by measuring the combined oscillator and prescaler supply current and subtracting the oscillator supply current. Calculated by measuring the combined oscillator and LO buffer supply current and subtracting the oscillator supply current. Calculated by measuring the combined receive and oscillator supply current and subtracting the oscillator supply current. With LNAGAIN = GND, the supply current drops by 4.5mA. Note 5: Calculated by measuring the combined transmit and oscillator supply current and subtracting the oscillator supply current.
