Features o 400MHz to 2.5GHz Operation o +2.7V to +5.5V Single-Supply Operation o Low Noise Figure: 6.3d B at 900MHz (MAX2680) o High Input Third-Order Intercept Point (IIP3 at 2450MHz) -6.9d Bm at 5.0m A (MAX2680) +1.0d Bm at 8.7m A (MAX2681) +3.2d Bm at 15.0m A (MAX2682) o <0.1µA Low-Power Shutdown Mode o Ultra-Small Surface-Mount Packaging General Description The MAX2680/MAX2681/MAX2682 miniature, low-cost, low-noise downconverter mixers are designed for lowvoltage operation and are ideal for use in portable munications equipment. Signals at the RF input port are mixed with signals at the local oscillator (LO) port using a double-balanced mixer. These downconverter mixers operate with RF input frequencies between 400MHz and 2500MHz, and downconvert to IF output frequencies between 10MHz and 500MHz. The MAX2680/MAX2681/MAX2682 operate from a single +2.7V to +5.5V supply, allowing them to be powered directly from a 3-cell Ni Cd or a 1-cell Lithium battery. These devices offer a wide range of supply currents and input intercept (IIP3) levels to optimize system performance. Additionally, each device features a low-power shutdown mode in which it typically draws less than 0.1µA of supply current. Consult the Selector Guide for various binations of IIP3 and supply current. The MAX2680/MAX2681/MAX2682 are manufactured on a high-frequency, low-noise, advanced silicon-germanium process and are offered in the space-saving 6-pin SOT23 package.
