3/4G_PAIN_HB
LPF for more
margin on Tx
spurious
3/4G_PAIN_MB
3/4G_PAIN_LB
4G PA input need LPF for harmonic rejection
B41 TRX
B9081 port4 is ANT (Pin to Pin DGAH74S03 partial 41 Band)
ACPF-8240 port1 is ANT
885049 port4 is ANT
B7 TX
B40 TRX
Bypass path
NTC3201 close to PA , and located in the same layer
60mil
VPA_VCC1 and VPA PMU need to be connected after Cap
For power LTE_VMIPI star connection
Thermistor / To sense board level temperature
Far end Cap. For PMIC stability
IF B34/B39 reuse TXM,
this path can be deleted
This path is no use for Sky77643
This path is reserved for 3M Co-PCB
(Change Sky77643 to other vendor's M/H
PA which support B34/B39 and TXM can't
support B34/B39 TXM reuse)
RFMD and Murata
have pin to pin products.
Please check latest
