CMX975 - 2.7GHz Up/Down converter

General Description

The CMX975 is an RF building block IC that provides multiple functions consisting of: RF PLL/VCO, IF PLL/VCO, Transmit Up-convert mixer, Rx Down-convert mixer, and LNA.

Key Features

  • 1 to 2.7 GHz Up/Down-converter Configurable image reject or normal mode Rx mixer Configurable sideband suppression or normal mode Tx mixer Combine with CMX973 to implement RF-to-I/Q transceiver 1 to 2.7 GHz RF / 10 to 500 MHz IF.
  • Integrated LNA 1.7dB noise figure at 1.5GHz 18dB programmable gain range.
  • RF synthesiser/PLL Fractional-N 24-bit divider Output range 350MHz.
  • 3.6GHz Programmable output divider Fast lock function Programmable charge pump current.
  • IF synthes.
