MAX2690EUB+ (MAXIM INTEGRATED PRODUCTS)

The MAX2690EUB+ is a low noise, 2.5GHz down converter mixer in 10 pin µMAX package. Thus miniature, low noise, low power down converter mixer designed for use in portable consumer equipment. Signals at RF input port are mixed with signals at the local oscillator (LO) port using a double balanced mixer. The RF port frequency range is 400MHz to 2500MHz and LO port frequency range is 700MHz to 2500MHz. The IF frequency range is 10MHz to 500MHz provided LO and RF frequencies are chosen appropriately. The IF port is differential, which provides good linearity and low LO emissions as well as providing compatibility with applications using differential IF filters, such as CDMA cellular phones. The mixer noise figure is 10dB at 900MHz, it draws 16mA at VCC = 3V and operates from a +2.7V to +5.5V supply. A logic controlled shutdown mode reduces supply current to less than 1µA making it ideal for battery operated equipment.
