Modulation bandwidth using analog I and Q input with LPF bypassed

If the DAC is disabled and TXINI and TXINQ are used as the analog inputs, what modulation bandwidth can be achieved if the LPF is bypassed using address 0x35 bit 6 (BYP_EN_LPF)?

Is this extended modulation bandwidth with the LPF bypassed the same for the transmit and receive paths (ADC disabled and RXOUTI/RXOUTQ used with 0x55 bit 6 set high)?

Hello,

Yuu would be able to achieve about 42 MHz (RF) BW. Same for receiver.

Best,

Great. Thanks for your reply. If and when I end up getting my boards together, I’ll be sure to provide feedback on any testing I do in this configuration.
