RF Micro Devices RF3404PCBA
The RF3404 is a fully-functional, integrated dual-band downconverter module for tri-mode CDMA applications. The module, which uses SiGe technology, features two complete RF downconverters with low noise amplifiers, RF SAW filters, TX LO buffers, and RF matching for PCS and cellular band frequencies. The mixer design allows for a common IF filter for CDMA cellular and PCS operation, and a second output for the FM output.| Part No. | RF3404PCBA |
