www.ti.com Physical Description 2.2 RX Operation 1. Set TR (J13) to logic 0. 2. Set PA_A SEL (J10) to logic 0. 3. Connect a differential LO source to the LOP/LON SMAs (or use an external balun). Set the LO to an appropriate frequency, with the power level between 0 to +4 dBm. Remember that for A-band operation, the LO input frequency is doubled inside the TRF2436; so, the LO should be set to half the frequency desired at the mixer LO port. 4. For mixer stage measurement: a. Terminate RFA (J9) an
