RFIC Mixer Downconverter Boasts Of Low Current Drain Spec

Usable for applications with an RF frequency range from 500 to 2500 MHz and an IF output range from 45 to 500 MHz, the TQ5M31 is a general-purpose mixer/downconverter RFIC for mobile phone, CDPD, ISM, SatCom, and WLAN data networks. The device uses minimal off-chip matching components while maintaining maximum application flexibility and high output Third Order Intercept efficiency. Small current drain, small physical size, and low cost make the chip well-suited for portable, battery-operated applications. Conversion gain is 2.0 to 3.5 dB, depending upon band of interest and varies by only ±0.3 dB over the full operating temperature range. Available in a 6-pin, SOT23-6 package.
