Hello. I have a problem with output signal (no signal).

LOIN&LOIP -4dBm (+2Vdc)

DSOP floating +0.6Vdc

QBBN, QBBP, IBBN, IBBP no signal (+0.5Vdc)

VPS1, VPS2 +5Vdc

RFOUT no signal (+3.4Vdc)

NC, COMM, EP connected to ground  plane via a low impedance path.

Supply current ~200 mA

I have 6 chips, but only one works correctly (manufacturing code 1552).

Another chip works correctly if I press on it.

Resoldering not help((((

Can you help me with this?
