CMX975Q4

Overview

The CMX975Q4 is an up/down converter from the RF Building Block range, operating within a frequency of 1 GHz to 2.7 GHz. It features a low noise amplifier (LNA), dual phase-locked loops (PLLs), and a voltage-controlled oscillator (VCO). The device provides a gain of 7 dB with a P1dB compression point of -11 dBm and a noise figure of 15 dB. It supports an intermediate frequency range of 10 MHz to 500 MHz and a local oscillator frequency of 700 MHz to 3 GHz. Powered by 2.7 V to 3.6 V, it operates between -40°C and +85°C in a VQFN-40 package.

Feature Summary

• Integrates LNA, dual PLLs, and VCO for complete conversion functionality
• Supports wideband operation across 1 GHz to 2.7 GHz RF frequencies
• Includes flexible LO generation covering 700 MHz to 3 GHz

Applications

• Wireless communication systems requiring integrated up/down conversion
