Other Parts Discussed in Thread: WL1837MOD
Dear Sir/Madam,
Due to component shortage, we have mix part# soldering (WL1835MOD & WL1837MOD) on a batch of PCB assemble on prototypes build.
Would like to confirm the below impedance behavior on ANT1 & ANT2 pins between WL1835MOD & WL1837MOD.
- WL1835MOD ANT1 & ANT2 pin to GND is 0ohm.
- WL1837MOD ANT1 & ANT2 pin to GND is Hi-Z.
Since don't have any RAW parts on hand, cannot verify above the impedance behavior is normal or not.
Not sure is it cause by the internal filter circuitry between Single Band (WL1835MOD) and Dual Band (WL1387MOD) application.
Need this information to confirm is there any PCBA issue (solder short or not soldering well).
Best regards,
Ping
