Hi all. I'm designing an SDR transceiver. I need a RF chip/module that at least contains PA, LNA and Tx/Rx switch. It should perform conversion between analog or digital baseband/IF signal and 2.4GHz radio signal. Modulation/demodulation will not be done in this chip. The radio signal is sent/received to/from an antenna. In short, I want the RF module in the figure below only. DAC/ADC can also be included inside: Antenna <--> RF Module <--> DAC/ADC <--> Baseband processing <--> ..... ------------------------- I've searched a lot but only seen some wifi/bluetooth/zigbee chip sets that indlude modem also... Do you have suggestion for such chips? Thank you.
