RF Building Block - CMX970 IF/RF Quadrature Demodulator IC

RF Building Block - CMX970 IF/RF Quadrature Demodulator IC
CML Microcircuits has released a new low power, IF/RF Quadrature Demodulator Integrated Circuit. The new CMX970 offers exceptionally low power consumption and high performance over the operating range of 20 to 250 MHz. Designed to meet the challenging requirements of Wireless Data and Analogue/Digital PMR/LMR radio systems, this product builds on the classic superheterodyne receiver technique to realise the ultimate low power IF/RF Quadrature Demodulator. The device can also be used in direct conversion applications in the VHF spectrum.

QAM RF Demo with 2 PE0002 Hosts

When the original QAM + RF YouTube video was created, our evaluation board recommendation for customers consisted of one PE0002 host. Since that time our customer recommendation for QAM + RF evaluation boards has evolved into using two PE0002 hosts. Consequently, the original video has been updated to reflect operation with two PE0002 hosts.
