MAX2440, MAX2441, MAX2442 900MHz Image-Reject Receivers

The MAX2440 MAX2441 MAX2442 highly integrated front-end receiver ICs provide the lowest cost solution for cordless phones and ISM-band Radios operating in the 900MHz band. All devices incorporate receive image-reject mixers to reduce Filter cost. They operate with a +2.7V to +4.8V power supply, allowing direct connection to a 3-cell battery stack.
The signal 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 (IP3) of up to +2dBm.
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 as an LO Buffer Amplifier Three separate power-down 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 in a 28-pin SSOP package.
Evaluation kits are available for the MAX2420 MAX2421 MAX2422. The MAX2420 MAX2421 MAX2422 are transceivers whose receive sections and pinout are identical to the MAX2440 MAX2441 MAX2442.
For complete transceiver devices, refer to the MAX2420 MAX2421 MAX2422 MAX2460 MAX 77d 2463 and MAX2424 MAX2426 data sheets.
