Product Description
The TQ5M31 is a general purpose RFIC mixer downconverter designed for multiple
applications including worldwide cellular and PCS mobile phones, ISM bands, GPS
receivers, L band satellite terminals, WLAN and pagers. The TQ5M31 is usable for
applications with an RF frequency range from 500 to 2500 MHz, and an IF output
range from 45 to 500 MHz. The integrated circuit requires minimal off-chip
matching, while allowing for the maximum application flexibility. Low current drain
makes this part ideal for portable, battery operated applications. The output third
order intercept efficiency is very high.
