`3.3 SCPC
`
`SCPC is an automatic initialization method that includes an on-chip gain adjustment routine to
`reduce Tx output power variation.
`
`SCPC uses existing digital pre-distortion (DPD) calibration information, which is run at cold
`
`eat.
`
`I Saturated PA (PSAT) power has very little (<1 dB) variation from part to part.
`
`I PSAT used as a reference to determine target power.
`
`I Runs in an open loop after part output power is determined.
`
`I Uses information already obtained during DPD calibration, which uses Tx/Rx loopback.
`
`I Adjusts output power gain settings on a packet-by-packet basis.
`
`I SCPC loopback path does not include external power detector circuitry or the internal power
`detector.
`
`I Open loop power control does not react to external loading or mismatch.
`
`I Open loop power control shows more consistent packet-to-packct power control.
`
`3.4 WLAN analog baseband interface — schematic
`
`I Multiplexing within WCN3620 and digital baseband le allows the same two differential
`pairs (I and Q) to be used in both directions —Tx and Rx.
`
`I The bandwidth is 20 MHz.
`
`I Very sensitive I and Q baseband signals have tight linearity requirements with limited Rx
`drive capability.
`
`I Reute as phase-critical differential pairs —equal lengths.
`
`I Keep signals three-line widths or greater away from each other.
`
`I Resistance and capacitance on each pair should be equal; total capacitance should be less than
`10 pF. Routing impedance is not critical, but 60 to 70 (2 is recommended to minimize
`capacitive loading.
`
`I Crosstalk should be less than 60 dB at 50 MHz (goal).
`
`I
`
`Isolate from digital logic and clocks with ground all around; treat similar to a controlled-
`impedance stripline. Route on inner layers and transition to outer layers at ICs as quickly as
`possible to minimize capacitance,

`The application programming interface (API) is used to program WLAN functions.
`
`The WCN3620 primary operating mode is determined by software. For each valid mode, the
`appropriate analog, RF, L0, and digital baseband circuits are powered on and unnecessary
`circuits are tumed off.

`
`WLAN is configured but not used; WLAN can be enabled quickly from
