errata from first build
update schematic and layout:
-
D114=50R
-
D122,D111,D119,D112: DNP
-
wrong labels PG_-5V / !PG_-5V:
- cut J102P16 from PG_-5V and connect to U102P1 (!PG_-5V) via wire
- rotate D108 and connect anode to VCC
-
PTT input at J2 (optional):
- J102P15 10k to GND
- J102P15 wire J2P16
-
OPV max. VCC 5V, replace with other part or remove them:
- all TLV6001: DNP
- -5VADJ: connect RV102 to VOUT_-5VADJ
- OC_5V: Q203 DNP
- OC_8V: Q303 DNP
-
standard connection for automatic PA drain/gate voltage sequencing:
- connect 3V3(P1) to IN_EN_+13V4(P7),IN_EN_+18V(P9),IN_EN_+20V(P11),IN_EN_+5V(P13)
- connect PG_-5V(P16) with IN_EN_+8V(P5) (enable PA drain voltage after gate voltage is stable)
