1 / 14 page ________________General Description The MAX2424/MAX2426 highly integrated front-end ICs provide the lowest cost solution for cordless and ISM- band radios operating in the 900MHz band. Both devices incorporate a receive image-reject mixer (to reduce filter cost) as well as a versatile transmit mixer. The devices operate from a +2.7V to +4.8V single power supply, allowing direct connection to a 3-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 (IIP3) of up to +2dBm. The transmitter consists of a double-balanced mixer and a power amplifier (PA) predriver that produces up to 0dBm (in some applications serving as the final power stage). It can be used in a variety of configurations, including BPSK modulation, direct VCO modulation, and transmitter upconversion. For devices featuring trans- mit as well as receive image rejection, refer to the MAX2420/MAX2421/MAX2422/MAX2460/MAX2463 data sheet. The MAX2424/MAX2426 have an on-chip local oscillator (LO), requiring only an external varactor-tuned LC tank for operation. The integrated divide-by-64/65 dual-mod- ulus prescaler can also be set to a direct mode, in which it acts as an LO buffer amplifier. Four separate power- down inputs can be used for system power manage- ment, including a 0.5µA shutdown mode. The MAX2424/MAX2426 come in a 28-pin SSOP pack- age. ________________________Applications Cordless Phones Wireless Telemetry Wireless Networks Spread-Spectrum Communications Two-Way Paging ____________________________Features o Receive Mixer with 35dB Image Rejection o Adjustable-Gain LNA o Up to +2dBm Combined Receiver Input IP3 o 4dB Combined Receiver Noise Figure o Optimized for Common Receiver IF Frequencies: 10.7MHz (MAX2424) 70MHz (MAX2426) o PA Predriver Provides up to 0dBm o Low Current Consumption: 23mA Receive 20mA Transmit 9.5mA Oscillator o 0.5µA Shutdown Mode o Operates from Single +2.7V to +4.8V Supply 900MHz Image-Reject Receivers with Transmit Mixer ________________________________________________________________ Maxim Integrated Products 1 28 27 26 25 24 23 22 21 20 19 18 17 16 15 1 2 3 4 5 6 7 8 9 10 11 12 13 14 GND GND GND TANK TXON PREOUT PREGND MOD DIV1 VCOON RXON CAP2 TXIN TXIN LNAGAIN TXOUT GND GND RXIN GND RXOUT CAP1 SSOP TOP VIEW MAX2424 MAX2426 TANK VCC VCC VCC VCC VCC ___________________Pin Configuration 19-1350 Rev 2; 2/99 PART MAX2424EAI -40°C to +85°C TEMP.
