Looking for AFE7500 datasheet

Other Parts Discussed in Thread: ADC32RF45, DAC38RF80

Hello,

I want to analyze AFE7500 with other transceivers. I don't see the detailed datasheet anywhere in the online. Please share the datasheet link if anyone have.

Thanks,

Muthu

  • The AFE7500 is not a public device and is not recommended for new designs. Alternatively, check out the TSW40RF80 reference design that utilizes an RF sampling transceiver.

  • Hi,

    We are looking for RF transceiver which is capable of doing 1000  frequency hops/sec and it should have 4 GHz to 5 GHz operating band. Does TSW40RF80 support for my rate of frequency hopping?

    Thanks,

    Muthu

  • Hi,

    The device you shared is having only high speed ADC and DAC ?
    Dont have RF knowledge?

    Thanks,

  • The TSW40RF80 employs the DAC38RF80 RF sampling DAC and the ADC32RF45 RF sampling ADC. These devices convert bits-to-RF and vice-versa so they are an RF transceiver.

    The RF DAC can support up to 5 GHz operation in second Nyquist zone with reduced performance. The analog BW of the RF ADC is limited to about 4-GHz.

    If operation up to 5 GHz is a must then these devices may not be well suited. There may not be a simple alternative device to suggest. There is a highly integrated 4T4R RF sampling transceiver that can support up to 5 GHz but it is a device intended for high channel count systems. Alternatively, you can opt for a more discrete direct conversion architecture using the TRF3704 modulator and the TRF3711-35 demodulator with appropriate DAC/ADCs. This approach is cost competitive and supports frequency hopping with the use of dual RF synthesizers.
